Found a fix for contacts message tone
Since upgrading to the official, OS 22.214.171.1249, I haven't been able to make a custom ringtone for messages, to stick. It would always revert back to a default tone.
My husband said to take the hyphen out of the contacts' mobile number. The text app doesn't recognize the hyphen so it will use the default tone. It worked! It's a workaround till we get this bug fixed.
This was very helpful, thanks for the tip....
My custom tones quit working after the OS update as well! I'll give this a try, thanks!
