Device Registration - Run Company Portal in Single App Mode until authentication

Justin Graham 

I am having the same issue also, which seems to have started today (25th, Australia).

For us, once you reach the home screen, the Company Portal app doesn't launch by itself as expected. I can swipe around the phone and launch any app I can, even though I have the enrolment profile configured in Single App mode. If I launch Company Portal, it will prompt for login as expected:

• log in, then after MFA completes, the app closes on me.
• I restart the app, it auto signs in and shows the "Get notifications" message. I press OK then when the iOS message appears to allow notifications I press allow.
• The "setup <company> access" wizard starts. I press begin for step 1 (get your device managed).
• I am then prompted by iOS to "enable location" for Company Portal, and no matter which option I pick, it will cause me to lose touch access, so I cannot continue to complete step 2 (checking device settings). I have to force restart the iPhone.
• Upon restart, Company Portal auto launches as I am now stuck in Single App mode. I am not prompted to complete step 2.
• I can check status of the iPhone and it completes successfully.

Intune shows the phone is completely compliant and all policies have applied but I cannot escape Single App mode on the phone no matter how much time I let pass, or any number of forced restarts,

On top of this, today has also seen a number of users' Outlook app suddenly stop working after it updates. Upon investigation it seems Conditional access suddenly thinks I have no app configuration policy applied for to Outlook, even though I have. 

Other MS apps (OneDrive, Teams, etc) seem to be fine unless you log out of them then try to log back in.

When you try to log into Outlook or any of the other apps, after the MFA portion, you will be presented with a "Error: Something Went Wrong [1001]" message. Not a good day for intune...
