Encrypted Application Services/Bridges currently leverage the m.login.application_service login type to create devices for users.
This API is not available in the Matrix Authentication Service.
We're working on a solution to support this use case, but in the meantime, this means encrypted bridges will not work with the Matrix Authentication Service. A workaround is to disable E2EE support in your bridge setup.
