iOS 18.2 imap sync broken

Two major issues, affecting mail from IMAP servers, on both iPadOS and iOS starting with 18.2 update

Emails that have been deleted or moved to another folder (from a different device) still appear in the inbox. Which specific emails remain differs between an iPad Air 2024 and an iPhone SE 3 both accessing the same IMAP server (Dovecot and GMail).
Mail counts are inconsistent and incorrect. "All Inboxes 3" but the individual inbox listings total 10 emails.

I guess Apple doesn't invest in testing any more...

iPad Air, iPadOS 18

I think there are/were multiple issues, which confuses diagnosis. As a workaround I had disabled imap-IDLE on my (Dovecot) mail server and my iOS 18.2 iPhone was able to get mail, but was still hanging at times.

After updating to iOS 18.2.1, I re-enabled imap-IDLE and mail seems to be working normally. It uses imap-IDLE (near-realtime delivery) when the mail app is open and fetches every 15 minutes otherwise. It gets the mail messages and alerts correctly.
