Can't paste mutiple rows into Quick Edit since recent changes

staregirl I would also have issues with pasting into the grid view. It would duplicate some of the top records and not complete the full list. I had an ticket open with Microsoft on this - we were able to record it, to show its behavior, but when we turned on the F12 diagnostic window, we could not get it to repeat - so they closed the ticket without resolution. I do find that switching to Classic Sharepoint mode is reliable (and I guess turning on the F12 diagnostic window is a jerry-rig ).
