Zoom for Intune SSO works with Edge and App Protection Policy only 50 %

[BettiBarsch]

Hello,

I have the following problem. [Unfortunately, I haven't really found anything about it here or I'm blind in both eyes - ]
I have an Android tablet (S6 Lite) with Android (13), which is fully managed via MS Intune. An App Protection Policy has been rolled out on this tablet to protect the company data.
I have installed Zoom for Intune so that the app interacts with the Zoom app. So far so good.
I was also able to make the desired settings via a configuration policy. When I want to log in from the app via SSO, the Edge opens as a managed browser. Until then, SSO also works. But when I press the button to start the Zoom for Intune app again, nothing happens.
In the app, under "Data Protection" in "Select apps to exempt", us.zoom.videomeetings and us.zoom.videomeetings4intune are stored.

Does anyone have experience with such a scenario?
Thanks for your help!
