cannot remove or edit additional email accounts in
besides my iCloud email account, and over time, I have added 4 more email accounts to Apple Mail. I find now in this latest upgrade, I can no longer edit any of those accounts. 2 of this accounts I have previously edited, and one I haven't used for years - yet - I can longer delete delete or modify any of them. If I select "delete off all devices", it is removed then pops back up 10 seconds later. I can't tell you have f____ frustrating this is. I need hep or Apple has to fix something because this is insane.
