How to fix this problem?
Best answer by Max
For this situation, I would advise you to try a network settings reset. In that case, the phone will get back to its initial settings connection-wise so it should be working as intended.
To do that, please go to Settings > System > Reset > Network settings reset.
I trust this information will help on your inquiry. Nevertheless, if you have any other questions or issues, please let me know! :)
