It puts my phone offline

This stupid app becomes disabled and requires updates from time to time, even it’s just updated from the App Store last night. If I don’t update it, all my apps lose connection because the VPN is disabled.
My phone is set not to use cellular data to download apps. As a result, when I am outside and MS Defender thinks itself needs an update, my phone is offline.
This is my personal phone. I can accept business apps are offline when the VPN is disabled. But, how dare you do block my personal apps?

To slow to update!

Very annoying, everytime this app needs updating it takes a half n hour sometimes to 15mins?! It is frustrating! I have so many apps that never take as long as this one.

Works great!

Battery hog

Latest update in October 2026 has skyrocketed background battery usage by this useless app which is mandated by a policy.
