iOS Mail client will show x number of unread emails for a folder, but webmail, Outlook etc. shows none. The only fix is to mark all as read, readd the account or force a resync. This is when using EAS.

We've had this issue for years and years, 100s of reports and never been able to resolve it. I myself have this issue all the time and it only happens with SmarterMail. My O365 EAS accounts dont do it, another account I have with an IceWarp server does not do this either. Our biggest source of complaints is from O365 users who migrate, then within a week or so start asking why folders are showing unread messages, when there are not any.

Does anyone else have this issue?
