IPAD stuck on intune company portal

Hi,

we've synchronized ABM with Intune. I configured enrollment profile for one Ipad and set

"Run Company Portal in Single App Mode until authentication" as yes, also I disabled "Sync with computers:".

Intune company portal installed on Ipad and is set in single-app mode, but when I want to log in I receive "intune company portal is temporarily unavailable" and I couldn't do nothing so I sent wipe task from Intune but it has "pending" status all the time. I also can't wipe it from iTunes, beacause of the disabled sync with computers. Any ideas how to resolve this?
