Auto skip many waypoints by itself while I was on route. [5.2.0 - 474]

@paul69 the roads may well be established but if one of the sets of map data contains data about a road being impassable i.e. closed for construction or if the map data weights a road with a different average speed then the calculation of route could possibly result in a different being calculated

suppose that's a fair point, one to remember for the future when arranging rides with others.
TBF this can be the only explanation as nothing else would explain it.Take note all who read this, forget about the online, offline, internet or no internet, debacle, check your maps, obviously before you leave home on your trips with your mates

hi @brian-mcg
just thought I'd give you a quick update. I checked with my riding buddy and yes you are correct, his version was quite a few updates behind. It did not occur to me to even check if he had done this.
I thought I was quite an experienced user of MRA, but it shows there is always something to learn.
Complete School boy error but not too proud to admit itI imagine this will be a good reminder for people to check the map versions.

hi @LennyO
calculated route when offline, may not be exactly the same as you planned.
not entirely sure what you mean here. Why would it calculate an already planned route. The routes are planned on the MRA website and automatically sync to the devices when NN opened, my routes do not change when I use NN, (lets not discuss seasonal closures etc)
And the fact that the only people who had it different are the ones using the offline navigation kind of proves it.
the one with internet access had the route changed on their device, not mine (without Internet), for me the route remained as we had planned on the laptop, we both had offline navigation enabled in settings
did not have routes as tracks.

@paul69 I say that because you or your friends may have options selected in the Functional preferences that adjust the route based on the real time road work or traffic conditions.
That also answers the second half of my previous post. -

@paul69 the idea of it being the maps is only a guess not a fact
you would need to do some testing before & after updating the maps to prove itBlackView BV7100, Android 12

if I had the time to ride those routes again, I absolutely would especially given the weather here at the moment, but we live 200 miles apart and work gets in the way
Personally I believe it was probably the maps, I agree, as as you wrote, it would need to be properly evidenced, (but TBF I am not really that bothered, this was just a chat to highlight the issue for others)
As I wrote previously, every single one of the functional settings were exactly the same, these were checked and double checked. There is no other explanation except perhaps IOS and android work differently with regard to navigation, -
So, as of now it seems we have no explanation of the core issue or any solution...
Is somebody working on resolving it or I have missed something?
Thanks, all!Positive emotions are worth every penny ;)

@LennyO
so it would seem, but if you are aware of it then you can pre-plan.think the lesson for me is, (when riding in group)
- ensure all have same map version
- ensure all settings the same
- compare the routes before riding off
- might consider all to use offline nav. (I do anyway)
to achieve, we must first attempt ✌️

@paul69 regards your point 3)
a simple check I do is to check the total mileage for the trip is exactly as expected
to do this I include the total mileage in the trip name somewhere near the start of the file name
when I open the file, the planned mileage should equal the file name mileage
when I start the navigation & the route is recalculated, if all is well the mileage should still be same / correctits not infallible as you could get a route change that adds mileage in one area, then a second route change that takes a shortcut & reduces mileage, so you end up with the 2 changes cancelling each other out
however the odds on that are low & a mileage check should alert you to any signifiant deviationsan advantage of thi8s mileage check is it works across devices, no matter what navigation device you are using
if the mileages for the route do not match, at least reasonably closely, you know that the calculated route you are looking at is going to deviate somewhere along the path from the planned routeBlackView BV7100, Android 12

hi @Brian-McG
I used to use that tip when I had an XT after transferring routes from MRA to the XT2.
but it's a good reminder
-
Today i rode the route again. Just to see if the same problem happens again. And it did. Same place same result.
I lost cell coverage and approx 500 meters later, point 42 was skipped to point 56.See the result in the screenshot below
(I use MRA Next only on Android Auto. Every comment, suggestion, etc will be based on my usage with Android Auto)

@M.-Schrijver send me a link to that route and if you want me to I'll have a look at it

The same as on the first page:

Approx. at point 1 i lost my cell coverage.
At point 2 I heard and saw the auto skipping to point 56This was in the town center of Uelsen

Jumping waypoints has been an issue for me for a while. I've had the issue with it skipping waypoints over several versions since the rewrite.
I have skipping waypoints and rerouting turned off.
I've noticed it when I'm doing a loop and an early waypoint and a later waypoint are nearby ~20 miles. It will jump to that point and not give any warning until it starts trying route me to the later point. I hadn't noticed the status of cell coverage but most areas I ride have poor coverage.
I made a forum post a while back and didn't get much response so thought it might be specific to my setup.

@M.-Schrijver My suspicion is that at that moment, point 56 was closer than point 42 and the app wanted to go there. What I always try to do myself is place a point after the turn at every change of street/direction. If I see that there are no points on a long stretch, I add a few (after a fork or turn). Then, if something happens, I can skip the points more easily, or, as in your case, prevent the app from wanting to go to a closer point. Personally, I have automatic point skipping turned off (so this doesn't happen) and recalculate enabled.
-
I agree that point 56 pretty close 42 is. And from certain point of view it is not that strange that MRA skipped to point 56. But....
1.
There was no reason recalculate. No roadworks, no deviation from my side. Me, the blue and white line were all still on the same road.
2.
The issue is reproducable. This means something is wrong. But what?
3.
When MRA is forced to recalculate (whatever the reason is). Why not recalculate to point 43. This is more obvious for the user.
