Traccar Android Client

We have a few devices all running different Android Versions like, Android 9, some 10, and most recently 11

The issue we are facing is that the normal Traccar app is not loading on boot and therefore not sending tracking information to the server, we have disabled Battery Optimisation etc etc without any luck

However if you open the app manually it starts to begin sending data to the server again.

We are therefore seeking someone to develop our own Traccar Android client that would install, show us the device identifier to put into the admin side and then run in the background indefinitely.
