I cannot upload custom app into organization because Mgmt.AppCatalog.LOBApp.Upload.BadRequest.UnknownTeamsAppManifestExceptionType error has occured.

What I tried:

• I tried to upload same app to other tenant but got same error.
• I tried to upload other app but got same error.

I'm also getting the same error trying to upload a custom app for testing.
It's passing the app validator perfectly: https://dev.teams.microsoft.com/appvalidation.html
