Acrobat for Teams no longer working

We are in the process of deploying Acrobat for Teams. Currently we have 4 users allowed to use the App in Teams. This has worked for a while. Today I wanted to review together with a colleague and we found the App is no longer working. When trying to open any PDF in Teams, we only get a white page. I tried the same with the Teams-Webclient and it says :https://documentcloud.adobe.com/msteamsintegration/main.html#/pageContext=homeTab ist eventuell vorübergehend nicht erreichbar oder wurde dauerhat an eine neue Webadresse verschoben.

I have checked in our Teams-Admin Center: Adobe Acrobat is on Version 2.0.3

Our Teams Version is 1.6.00.27573

I have also reviewed permissions for the Acrobat App and found nothing out of order. Please advise
