iCloud Mail not syncing across devices

I've been using iCloud Mail for years now. I have a MacBook Pro, iPad and iPhone 11 Pro. About 3 weeks or so ago, my email stopped syncing. All devices receive the emails, however; when I delete or read emails on my iPhone, this doesn't sync with my other devices. I haven't made any changes to my accounts to cause this, so I am at a loss. I've tried signing out of iCloud on all my devices and then logging back in, to no avail. If I go to iCloud.com and read/delete emails, then my devices will update.


Please help!!

MacBook Pro 13", macOS 10.15

I had this exact problem on the new iPhone 12 Mini.


I was receiving email across all devices, but any changes made on the phone wouldn't reflect on the other devices, inc. laptop and iPad. (Changes made on other devices synced just fine - even on the iPhone.)


I tried EVERYTHING: signing in and out of iCloud (on all devices), deleting and reinstalling accounts, etc.


The solution was to DELETE THE MAIL APP ON MY IPHONE. I reinstalled it and suddenly everything worked fine, syncing between all devices. Hope this helps.
