Yes, I have the same issue. I work everyday and can't do without a working phone.
The issue for my now occurs half of the day and the other half of the day the Apps work.
This really drives me crazy. I have always had such a reliable phone! Please fix this Microsoft!
EDIT 21-1-2018: I've run my device past the Device Recovery tool on PC ... now installing every single update ... this is taking me alllll day. Really hope it works!
