Hi Yesterday I signed out of iCloud, iMessage etc and erased all content and settings on my iPad mini. It has now gone to a new owner. However, my new iPad Air 2 is still showing tabs open on the mini (last tabs before it was wiped) Does it just take a while to update? I have checked my devices on Apple ID website and mini is no longer present. I'm also soon selling my MacBook Pro and wonder if the same will happen or how to avoid?
