Getting error when trying to intsall Forge apps from Marketplace

I am getting this error when trying to install a Forge app from the marketplace - “It might just be a hiccup. Try again in a bit.”
I tried this on a couple of Forge apps. Is this a current known issue?

Atlassian confirmed this was a known issue. Should be fixed.

Does this fit into any of the error scenarios described by this link:

Or is this another new scenario that I’m not aware of? (As I’m happy to document it)

Is there a Jira issue that I can follow for this problem?
