The total mileage is reset to zero

On all devices, the client is downloaded from Google Play.

We're talking about the server mostly.

OK, then I'm not sure what might be an issue. Are you sure you didn't recreate devices?

I didn't do it. On another device, I installed and launched the application the day before yesterday, but this morning there was also a problem in the form of zeroing "totalDistance". Today I will try to reinstall the server part and upload the database there, I don't think it will help, but I have no options left to solve this problem.

Reinstalled the server part but recently noticed the problem again.

Unfortunately no idea what could be the problem. Works fine on our test server.

Thanks anyway. Otherwise, I like the functionality of this project, it's very convenient.

Hello. Tell me, are there ports other than 5055 and 8082 that should be opened? I think it could be a server, now I will try to use a demo server on these devices.

For the OsmAnd protocol? NO.

Thanks.

1. Is there access to the BD on the demo server.
2. Is it possible to change the configuration?

No and no.

Thank you very much. I think that's it.
