Moving a page displays an error:
"Page tree error
Got unexpected response from the server. Please check logs for details."

The page moved but you'll need to manually refresh the PageTree to see the move by clicking the Reload tree from server button at the top of the PageTree. You'll still need to publish the move, as usual, before visitors will see the any change.

Attempts to edit the unit's main page record while there are other draft records pending on that page will display a
"Sorry, you didn't have proper permissions to perform this change."
error. As of now, you'll have to cancel or publish those pending draft records before you can edit the page record.

The system is holding the draft record in a position in the pagetree where you do not have access. The issue has been reported to TYPO3 developers.
