Similar experience, Emma. But the problems began before the release last week. I have submitted two tickets related to proofs—inability to close a proof using the "x" in the top right corner, and time stamp of latest proof added to a version stack was not being reflected in the list view of Documents tab—but was correct in the Summary panel. The latter has been resolved, but resolution for closing of the proof is still in progress.
Neither of these issues are captured on the Known Issues page. It would be valuable if this page were updated with current and specific information reliably. It would also be useful if, as you experienced, there was a better filter on the Search feature for this board.
I found this thread when searching Community but it dead ends with a response that this is "new expected behavior" which is neither useful nor true.
