App Updates too much

It is annoying that app updates like weekly. It seems the app updates constantly and It’s annoying not able to make calls when I have to manually run diagnostics to see that the app is not on the updated version. So I update app then run diagnostics again before making a call. Sometimes the call is urgent and it’s being delayed because I have to do additional steps to update the app before making the call

Hard of hearing

The app is very helpful to me. Even though I can only hear a little bit. I can still understand what the person is telling me because of the caption. Thank you
