PROBELM: The Mail app that I use for G-mail account stops receiving or sending messages. I have Mail app version 14.0. I also have the G-mail Web version, that works fine, but does not have any of the "bells and whistles"--easp. Mailboxes--that I need to file & save e-mails & attachments in one place.
FAILED SOLUTIONS, NO PERMANENT FIX: With Apple support help, have removed and reinstalled g-mail account 2X in April, like every two weeks, and now it's failed again.
POSSIBEL CAUSES?: I have noticed that this happens BEFORE Apple updates the IOS; just got note that update Big Sur 11.3.1 "will be installed tonight." But previously the failure did not fix itself after the auto IOS update.
What to do? Tired of spending time with Apple support (40 minutes), finding that all settings are ok, and that only remedy is to "remove and reinstall." The problem with the fix is that, with many messages stored in mailboxes over a decade, every message has to reload when the app reinstalls.
QUESTION: Could cleaning out all my "old mailboxes", with info dating back to 2012, help (some 2000+ messages asa I recall)??
