Hi,

**Issue:**

- We recently installed the “Zoom for Lightning” application from Salesforce AppExchange to sync Zoom webinar data with Salesforce.
- As part of our Proof of Concept (PoC), we initially connected our Zoom account to a Salesforce Developer Org, where both Zoom Webinars and Zoom Webinar Registrants were successfully synced.
- However, after disconnecting the Zoom account from the Developer Org and connecting it to our Sandbox Org, we noticed that Zoom webinar data is no longer syncing.

**Error Message:**

- No error messages are received.
- Zoom webinar data is not syncing in the Sandbox Org after reconnecting Zoom.

**Steps taken:**

- Connected Zoom to the Developer Org → Webinar Sync was successful.
- Disconnected Zoom from the Developer Org and connected it to the Sandbox Org → Webinar Sync failed.
- Reconnected Zoom to the Developer Org → Webinar Sync worked again.
- Disconnected Zoom from the Developer Org and reconnected Zoom to the Sandbox Org → Webinar Sync failed again.

Would appreciate your guidance in troubleshooting and resolving this issue.

Thanks
