Upgraded my 640 to 10 with some weird goings on. Initially everything seemed ok, favourites showing in edge, glance screen and extended extras menu. I decided to backup the phone and carry out a hard reset. Did this and restored from backup. Now I have no edge favourites, no glance and the extras menu has reduced to half it's original size??? Tempted to go back to 8.1 and upgrade again, this time leaving out the hard reset after. Anyone else experienced this?
