Thanks for the feedback. Unfortunately, the steps listed out in the link did not work.
I do not uses do not disturb or a VPN on this phone. (I double checked both for certainty).
For clarity, I’m receiving notifications for all other apps.
I currently have an MS exchange account that I use for work on the nail app. I previously was using the outlook mail app and was receiving notifications on that app, however decided to switch to the native mail app for other reasons. Since that time I’ve deleted the outlook mail app.
ive uninstalled and reinstalled the Apple mail app which did not work either. I fell like I’ve tried every idea out there.
