Mail notifications on iPhone 13 Mini
My wife's iPhone 13 Mini frequently stops notifying receipt of new emails, although text notifications remain OK. The ONLY way I've found to put this right is to restore the device from the most recent backup, after which email notifications return. It's becoming a pain to keep re-instating Face ID, etc. just to get the device to do something that it's supposed to do. Any suggestions as to the cause of this, please?
