Here are a few steps and considerations that might help you resolve this issue:
- Verify Teams Optimization is Enabled: Ensure that Teams optimization is enabled on the golden image. This includes installing the AVD optimization components correctly.
- Check for Updated Teams Version: Even though you mentioned that you have installed the latest version of Teams, double-check to ensure that the deployed version is specifically optimized for AVD.
- Registry Settings: Sometimes, specific registry settings need to be configured to ensure that Teams is aware it's running in an AVD environment. Verify that the necessary registry keys and values are set correctly.
