How to setup Microsoft Managed Home Screen in kiosk mode on Dedicated and Fully managed devices

I'm asking here, because I can't find a better place to do it.

In your documentation, Teams is clearly a featured App. I have followed this and other documents with the intent of supplying a number of mobile devices to our hospitality staff, specifically for Teams. As such, we had opted to go with the Samsung Galaxy XCover Pro, for it's Walkie Talkie/PTT button feature.

Here is what I've encountered. Device is configured Dedicated with AAD Shared Auth (understand it's Preview).

• Teams cannot receive calls when the device is idle. This makes the solution effectively DOA.
  • Documented here: https://docs.microsoft.com/en-us/mem/intune/configuration/device-restrictions-android-for-work
  • "When using multi-app kiosk mode, dialer/phone apps may not function properly."
• Managed Home Screen login does not seem to support SMS Auth.
• Office and Office Apps appear to crash in Kiosk Mode.

Any help or could you point me to the arena to have this discussion?

Additional note on the Galaxy XCover:

• Use of PTT button requires a subscription to Samsung's Knox Config Platform.
  • I get this is a 3rd party hardware requirement, but MSFT is advertising this device as if it works OOB.
