Testfligh - Unable to install app

Hi Apple developer team,

We contacted support and was asked to contact the developer technical team. We can provide Case ID if needed.

We are having an issue we did not encounter before. Once we want to install or update our new test build in testflight we get the following error: App name could not be installed. The app is not availible or does not exist.

We updated the app several times with new builds but the issue remains.

Thanks Dieter

Have you been able to resolve this? I am having a similar issue but not exactly the same.
