Just move them to cloud and redownload. No need to reregister entire device. I had the same AB issue yesterday and this worked for me.

Steadily getting used to all the changes and adjusting. Nothing is perfect so I'm taking a positive attitude about the update. Getting mad at BN for something everyone has been clamoring for so long is silly. There are some pretty great things about the update, the others will either be fixed later or I'll live with it.
