I would like to report a bug.
My morena fairphone 3 could not find my GPS position.
The error occurred after I disguised my location (Advanced Privacy) and switched back to the real location.
It was due to the SIM card data being switched off.
Allow mobile data of the sim, and switch it off again. That was the solution. Restarting, giving extended permissions, etc. - all did not solve the problem.
Maybe my report is useful?
