Just checking on Image Tag availability. The last update was end of May for availability MC272451. It's not showing in our GCC tenant yet and were well into June. The Roadmap has it GA last February - ID 88708.
We have exactly the same here, we are tracking the changes in our backlog to be informed about changes and here we just don't see any change of the behavior even if it should be in GA... Would be interesting, if others have the same problem as well.
