The changelog for version Version 3.22 says "Failed Notifications (e.g. Mobile Data is off when receiving an MMS) now play a (failed) ringtone". The tone that's currently used isn't the notification sound I chose in my Textra settings, and it isn't the default notification sound for my device -- I can't even figure out which sound it is, much less change it to something else. Is there a way to change this?
