“Apple technical support assigned me a case number and told me that the only solution to fix not getting a mail sound notification is to completely erase my phone and set it back up from scratch (not from a backup)… to fix a mail sound from one of their apps? There must be an easier solution but additional calls to Apple say that this is the only solution.”
I have spoken with several people and have read in other Apple forums that have to do with this problem and the above mentioned solution/fix HAS NOT resolved the problem. (Erasing your phone and setting up from scratch).
Hard pass, based on what I have heard and read in other related Apple’s forums.
There MUST be a simpler solution.
