Hello.
I have a question I was wondering if anyone else have encountered. I have developed a Power App for Teams app that we've been using for a while without problems. Everything worked fine in the old Teams, but in the New Teams, we get an error when trying to add the app to a tab in a Team.
If we click "+" - "Get more apps" - "Built with power platform" - Find the app and click add to a team, as shown below, we get the error in the next picture.

Something went wrong when loading tab configuration dialog, please try again later.

The app now shows up in the app overview for the team and can be added without problems, but the users can't do this trick everytime. It should work directly from "built with power platform", as it did with the old Teams.

Have anyone had this issue? Know of a solution?
