Right now, I'm only using the installed web app on my Tab S9 Ultra. Right now the Android app is too unoptimized to even consider using it as default and is only installed for notifications.

Unfortunately, the installed web app on Android doesn't seem to support notifications at all like on the desktop. I enabled every setting possible but I don't receive any notifications. Please consider adding working notifications for the mobile version of the web app.
In the installed mobile web app from Outlook this feature exists already.
