Request for Support on Authentication Issue in DTLive App

I have recently purchased the DTLive app from Envato, and it is working well except for an issue with the authentication process. When attempting to log in, the app gets stuck on the "Please Wait" popup. However, it does save the chosen email to Firebase.

I have followed the steps exactly as outlined in the documentation, but the issue persists. Could you kindly assist me in resolving this authentication problem?

I would appreciate any guidance or troubleshooting steps you can provide.

Thank you for your support.
