Custom App is not working anymore in Teams 2.0
Hello, we created a custom app for Teams to connect to a SPO Site directly from MS Teams. This app worked well for the last weeks. But now it could not be opened by many Teams 2.0 users. The error message: "There was a problem reaching this app" The custom app is working in Teams Classic, Teams Web, Teams Web New.. But not anymore in Team 2.0. It was already working for the users.. manifestVersion":"1.16 contentUrl:https://mycompany.sharepoint.com/sites/SiteName validDomains":["mycompany.sharepoint.com"] We already tried to clear the cache, reset the app, reinstall the app.. Nothing helped so far...
