I’m not using a VPN, but thanks for your suggestion.
Tried it with and without VPN. Same either way.
I had the same issue after updating my software to OS18. Powered down my phone and back up, and it was resolved.
Today I reset my Network Settings on my iPhone 14Pro iOS 18.1 and also re-built my mailbox in Apple Mail on my MacBook M1 Pro. This seems to have fixed the issue!
If it recurs, please post back here.
Unfortunately the issue has returned.
I’m home and just turned off Wi-fi on my phone and Mail connected to gmail accounts immediately. Got all of the emails I was missing. Thanks!
That worked for my, thanks!
