The "Remove data from previous versions" just disappears

The popup just disappears when i click “Yes” on the notification.

I have exactly the same problem. Any solution found yet?

Me, too.  It does not matter what button I press (yes, no, later), it  just asks me the same thing next time.

The old data can be removed in the Menu>Tools>Settings>Storage window.We’re sorry for the inconvenience.
