Rights approval
After the first successful login, the system prompts you to give some approvals so that the app can send and receive SMS messages and access files. Confirm the respective queries with Allow.


You will then be prompted to allow information to be displayed over other apps. This is necessary so that the app can display a message on the screen when alarms come in, even if you are currently in another app.

Therefore, make sure that the option Allow Display Over Other Apps is activated. Then tap Back to return to the main screen of the app.
