Why does my wallpaper keep changing after marshmallow upgrade on s6?

[AC Question]

Since I upgraded to marshmallow on my s6 I handed found that it takes much longer for my emails to sync/download, and my wallpaper and lock screens keep reverting to the Samsung default backgrounds.

I have the same issue with my Note 4 since upgrade to marshmallow. My lock screen image keeps changing no matter what I set it to. Driving me crazy. Any ideas?

I would do a backup and then a factory reset/restore. A good idea after any major upgrade. If it still occurs, do a factory reset and then install apps manually.
