Fix copy & paste bug when Handoff (Universal Clipboard) is enabled
When Handoff is enabled (which also enables Universal Clipboard) and you are signed in to iCloud on your Mac and a nearby iPhone or iPad, Excel will freeze when you try to copy any cell. The spinning beachball will appear for 3-4 seconds and you can't do anything while this is happening. The bug also affects Word. This happens even on a Clean Installed system so it is not a 3rd party conflict.
I've posted more details and a video of this happening on the Microsoft Community Forums:
I've tried to report this bug but it seems impossible to get a ticket open that goes to the developers, so I am posting here hoping that others will vote for this issue so it can be fixed.
