Used to work great, but now all of a sudden I cannot set a custom ringtone for a contact. I get a "Please open storage permission". When this contact calls, there is no sound at all... I just get a missed called notification later. The app has storage permission. In fact it has every permission it asks for, none denied :-( Oh, and the email address shown as the Developer Contact here in the app store is no longer in service... So... this appear to be the way to contact them I guess; Leave a bad review... Update March 2022: Ability to use Bluetooth headset hasn't worked in months... reinstalled... cleared cache... tried a new phone... tried a new headset... upgraded phone to Android 12 (Google should know about this OS, right?)... Nope... just not working... Want to take a trip back to the mid 20th century? Try Google Voice...
