Looks like Slimcore Teams VDI optimization is now available for Citrix with macOS clients. https://learn.microsoft.com/en-us/microsoftteams/vdi-2 Is it working for anyone? I have all the correct versions and the client-side plugin installed, but Teams is still using the "old" HDX optimization.

I am positively striking out. I don't even see the slimcore checkbox in 2508 or 2511. I'm trying 2603 preview with no luck there either. Microsoft has a direct download link for the plugin but installing it doesn't make a difference either.

Maybe the rollout is completed yet? Microsoft 365 Roadmap | Microsoft 365
