I called it out because Google Workspaces follows a very formal process for rolling out features, including a roll out schedule, etc... which are normally sent to Google Workspace Admins. "General availability" has a specific meaning to Workspace admins in terms of adopting new functionality, and Duet isn't following the typical release/roll out process.
Maybe we'll be surprised and they'll email the traditional feature roll out email to Workspace admins later this week
That seems maybe excessively nitpicky? You need to "request access" to ChatGPT too... Were you denied or ignored when you tried?
