This frustrating matter is possibly resulted by the extra permission on your Android device called "Display pop-up windows while running in the background".
Here are steps to check and turn on this setting:
- Step 1: Open Settings app;
- Step 2: Search keyword "permission" > Open "Permissions" (App/Permissions) > Go to "Other permissions";
- Step 3: Search or Navigate to Driver app (your app's name);
- Step 4: Roll down to "Display pop-up windows while running in the background" > Click on this setting & select "Accept";
