Hi @csm , thanks for providing the versions. I noticed that the sdk version you were using is already outdated. And from Meeting sdk 5.0, only Zoom clients which support GCM, are able to join Zoom Meetings, loginWithZoom(email, password) is no longer supported.
You can find more information about this update in this link:
You can now authenticate users using Proof Key For Code Exchange (PKCE), please see our documentation on for PKCE implementation guidance:
