I have an iPhone 12 Pro (iOS 17.1.1) and Apple Watch 3 (watchOS 8.8.1). I have been having this problem since late September, and it has been concurrent over multiple updates on my watch and phone.

I am using the default mail app with a Comcast and a zoho email account. I have it set to fetch every 15 minutes. I am still receiving emails and they are in the mail app, but I am no longer receiving notifications just when I’m wearing my watch.

If I am not wearing my watch I get the normal notification mail preview on my phone Lock Screen and everything acts as normal. The second I put my watch on I don’t get notifications on my watch or phone Lock Screen.

I have tried both “mirror my iPhone” and “custom” under the Mail settings on my watch. I also have all the notification options turned on on my phone, and also have alerts, sounds, and badges turned on for that specific account.

I have unpaired my watch and set it up as a new one. I have also tried restarting my phone and watch after changing settings in hope it will fix it. The only things I haven’t tried is restoring my phone from a back up, and deleting the mail accounts and setting them up as new ones.

This seems more like an issue with watch settings, but I don’t know what else to try. Has anyone else experienced this issue, or have any suggestions?
