Notification Icon not showing with new messages

[JAK77]

Long time Aqua Mail user here and switched to OnePlus 9 Pro love the phone.

Since I made the switch a few days ago I can't get the Mail Icon app to show in the notification area to alert me of a new message. I have tried every which way.

I even get the little icon that shows up to show the progress when I send a message but nothing doing on getting the app. I get notifications there from other apps.

Try to refrech that and see if it solve the problem and clear the cache !

Cleared the cache in the settings for apps.

Just today it started not syncing my mail which is an EWS and it always synced every five minutes.
