Cannot upgrade our Prisma-hosted cluster. The new version drop-down does not work / is not selectable. Tried Safari & Chrome.

The newer version are not cloud ready yet and this is expected at the moment. They are expected to be cloud ready in a couple of days.

I just wondered, as they are active on the public cluster.

Yes, they are almost ready, we are indeed monitoring them on the demo servers! :)

Excellent, thank you for the info 👍
