Hit or miss. At the end of 2021 it started having notification center issues. Like sending hundreds of duplicate or stale notifications. I could go into my email, delete some new e-mails and then close outlook. Then hundreds of notifications pour in for those deleted emails going a week back. Got a new phone and the notification problem still is an issue on a new install. On this new phone, pixel 6 with all updates now outlook just opens to a black screen most of the time. WTH happend?
