Solution that worked Comcast and Samsung Sync issue

My samsung S21 Ultra phone and Galaxy watch were not syncing with comcast email account.  This is what I did and so far has been working since 8 AM today.

Phone

1. Cleared email cache

2. Deleted email account on phone

3. Uninstalled Samsung email in play store.

4. Power cycled phone

5. Added back comcast email account 

6. Installed Samsung email from play store.

So far still good

Watch

From wearable app on phone removed email app. Power cycled watch readded email and it worked and I started getting notifications.

Hope this helps others
