@Corjan-Meijerink In my search for for why I was having problems, I found out on an Android device (maybe Apple also but not sure).
Battery optimization directly restricts your phone's GPS and background processing to save power, which actively breaks real-time features on navigation apps like MyRoute-app.
I set it to unrestricted and everything worked 3 minutes later when I reached my bike. I am not sure if Android changed it when I did the update? I had the same phone and it was working fine until I did the update. Here are the symptoms I saw immediately after 5.1 update. I had no speed indicator at all, didn't even register. I thought this was the only issue. I created a ticket with MyRouteApp and was responded to, asking me to delete and re-downloaded and install so I did. Went thru all the permissions again. Jumped on the bike Monday morning and made a simple point A to point B route, where I already knew where I was going. I always set my first way point away from my house just in case my GPS is acting funny and needs time to catch up. When I crossed the first waypoint my planned route did not recognize it. I jumped on the freeway and noticed it was trying to re-route my back to waypoint #1. I also noticed the arrival time was not getting any lower, along with the gas stations were not changing distance. I also noticed I had no turn by turn directions. I could see my route on the map and it was guiding me with the colored line on the screen. This part was accurate. when I arrived at my destination I typed in an address of the next destination. I had the same results. Later in the day, I went into my saved routes and clicked on a ride I have already did. Same results. Came home did a little A.I. Google search which walked me thru checking a few things. Everything was correct except for that battery optimized thing. I hope this helps and I hope I was able to give you good feedback here. I really enjoy your product. I belong to a riders group and I am trying to get all the guys to subscribe to your app. I think it would make our riding a lot safer and more enjoyable. I am even going as far as having a training class to show them some of the tricks I have learned over the year!
