This wouldn't be an issue if the App was stable, reliable and didn't reset the route numerous times during a ride. I will continue to use TomTom Go app until I can be confident that these issues have been fixed, fingers crossed that the new version of the MRA Navigation App is an improvement on the current build.
I guess the only solution is forcing the route by adding more and more shaping waypoints.
@Nick-Carthew I use an Android so I'm oblivious to the iPhone experience 
Is there a difference the way a route is calculated between Sat Navs? Multiple riders used the identical route edited in MRA, edited as TomTom, compared with HERE & Open Street maps, everything was checked and double checked, differences and errors were corrected
While on the TomTom Rider 550 user was directed on an unnecessary detour while other users (older TomTom Rider, Garmin Zumo XT and TomTom GO) were routed faithfully to the MRA route.
Is there a setting on the TomTom rider 550 that could have meant that it interpreted the route differently? Why were they the only rider that was sent on this detour?
I have had problems when transferring Routes via TomTom MyDrive and syncing with TomTom Go... The route doesn't always appear in TomTom GO My Routes Menu first time, it seems that you have to un-sync the route in MyDrive and re-sync it again. It works for me.

@Kudee I will be using the app again on a tour this coming weekend so I will use the route option navigate to closest WP or specific WP # and load the maps into TomTom Go as a back up
@Hans-van-de-Ven-MRA-Master No, often it's me removing the phone from the mount with the app still running and turning the display off while it's either in my pocket of in storage
It's maybe that I'm doing something wrong when planning a route in MRA planner. But when I navigate any route but stop at a waypoint (shaping point) or an unscheduled stop, the route recalculates and tries to navigate me back to the Start Point. I have to pull over and using the Navigation app I edit the route by deleting all the waypoints I have already passed. Very frustrating and I end up having to import the route into the TomTom app and select drive to nearest point option when starting.
It was more related to being able to plan a walking route and to get an idea of distance and timing and to look at the Route Track whilst on the walk to see if I'm deviating off course... I appreciate that my needs might go beyond the capabilities of the app, it's not a deal breaker, just my curiosity is it possible?
