Suddenly this morning (after my M1 MacBook Air ran overnight until it was out of battery, although I doubt it's related), many emails (only in my iCloud account) won't load in Mail this morning. They open, but the windows stay blank, some say "loading." Tried turning Private Relay on and off (since that seems to be a culprit for many things cited here), but no difference. Have restarted, rebuilt mailbox, etc.
Never had this before, and several of these are major-source newsletter that have worked every day until today. Also have discovered that searches in Mail are suddenly (new today) not working for iCloud mail.
Anyone else have anything like this? Any fix? Thanks!
