Webex and Zoom Known Issues
Overview
When upgrading to the 64-bit version of Citrix Workspace App (CWA) 2603, there are known issues affecting the Webex VDI and Zoom VDI optimization. These issues apply to both manual upgrade and auto-update scenarios.
For auto-update, the 64-bit architecture requires CWA 2511 to be installed on the endpoint, with the update to 64-bit architecture enabled through Global App Configuration Service (GACS).
Webex VDI Plugin
When upgrading to the 64-bit version of CWA 2603, the Webex App VDI Plugin is not automatically uninstalled or updated to support 64-bit CWA. You must manually uninstall the Webex App VDI Plugin before upgrading. The Webex VDI Plugin Installer Engine is uninstalled during the upgrade process but is not reinstalled, as 64-bit CWA does not currently include the Webex Plugin Installer Engine. The 64-bit version of the Webex App VDI Plugin can be downloaded from the Webex VDI release notes page.
Zoom VDI Plugin
After upgrading to the 64-bit version of CWA 2603, the Zoom plugin may not be optimized when connecting to your Citrix Virtual Desktop. To restore the optimized Zoom experience, complete the following steps on your local device:

- Uninstall Zoom VDI Universal Plugin (64-bit).
- Reconnect to your Citrix Virtual Desktop and start Zoom.

If uninstalling the Universal Plugin alone does not resolve the issue, complete the following steps:
- Navigate to Settings > Apps > Installed Apps.
- Uninstall both Zoom VDI Universal Plugin (64-bit) and Zoom VDI Plugin Management (64-bit).
