I’m encountering an issue with a published OAuth app in the Zoom Marketplace where only the app creator (myself) can authenticate successfully. The goal is to enable any Zoom user to log in and access the app.

Here’s the current implementation flow:
1. Users select Zoom authentication on my web app.
2 .They are redirected to Zoom for login.
3. After login, Zoom redirects them back with an authorization code.
4. Backend exchanges the code for an access token via Zoom’s OAuth API.
5. The backend uses the token to retrieve user details (email, username).
6. Finally, a session token is issued to the frontend.

Details about the app:
App Type: User-managed
Scope: user:read
Redirect URL: Correctly whitelisted
Status: Published and marked as “active” in the Zoom Marketplace

Despite this setup and the app being live, authentication still works only for my account and fails for all other users.

Could you please assist in identifying why this limitation persists? Are there additional configurations or permissions required to ensure that all Zoom users can authenticate successfully?

Thank you for your assistance!
