This thing is telling me to sign up for a Microsoft 365 account. Well, guess what. I already have a Microsoft 365 account! I have all the other premium MS apps installed with no issue. And, yes, I logged into Microsoft Defender with my 365 account, but it's acting as if I don't have a 365 account! What gives?! I'm really annoyed by this! What's up, Microsoft?!!! Update: problem has been resolved.

I don't know why there are so many bad reviews for this app. The persistent notification lets me know the app is still doing its job. And most people have Microsoft 365 if you're in the MS ecosystem for the app to work. Nothing in life is free. The app is fast and I don't notice a performance impact. UI is insanely basic (for better or for worse). My only beef is that if their login servers are having issues, the app will stop working.

Pretty cool but it would be nice get some more details on the added devices. As single location to track security for all my devices would be really nice. Also I added my computer to the same account and it just shows unknown n xt to the shield. I assume this is supposed to be the protection status but it's not updating on my Android phone. Uninstalled due to pay wall.
