iOS 15 mail app won’t sync read/deleted emails
Hi. For some reason my iPhone X has stopped acknowledging that I have read or deleted emails on the desktop app. I have one gmail account. I use Mail in OS X and iOS.
The OS X mail desktop app still behaves as expected and reflects the state of my Gmail account when I check in a web browser.
I have deleted and reinstalled the account from Mail on my phone (where the problem is happening) numerous times, have checked the settings in Mail, Settings…everything seems to be ok.
This behaviour happened out of the blue. No update was done, nothing appeared to change, it just stopped operating as normal.
I have since updated to the latest iOS 15.4.1.
Still no change. Any help greatly appreciated as it’s driving me a bit mad.
Many thanks,
Tim
