Hello together

We have a Problem with the Servicedesk+ App for IPhone and Android.

The Problem is that we can only opening our Incidents but not our Tasks and approval.

On my IPhone i have the following Error Message: Request failed unauthorized (401)

On the Android Phone we become only a message with ERROR.

I have Admin rights in Servicedesk+.

What can we do to solve the problem?

Thank you and kind regards
