  1. 2nd problem within 3 weeks with iOS Mail app. First the ALL MAILBOXES folder was empty so had deleted all accounts and app, and soft reset and reboot, and reinstall and re-adding accounts. That seems fixed but now this issue “No Sender” No Subject” on email of multiple accounts I have, I don’t like to have to keep deleting and reinstalling accounts and app and doing reset for these errors. I’m playing now with the idea of using Outlook app. Not perfect either but I’m using Outlook anywhere else including Android anyways so what gives,..
