All users (including Admins) are no longer able to assign work items to other users - can only self-assign. This was known to to be working at 0900, but then stopped. There have been no permission changes, and it is affecting all users across all projects. Atlassian is not reporting any issues on their platform - is anyone else seeing this behaviour?
In addition, all Spaces are showing no users as having access - although users can still view work items within those same Spaces.
