"Application! has stopped" errors after recently upgraded to Andriod 7.

"Application! has stopped" errors after recently upgraded to Andriod 7.

I have a Nexus 5x running Andriod 7. Since the Andriod 7 upgrade I'm getting ""Application" has stopped" errors sporadically - across multiple applications. (Spotify, S Health, Samsung Gear, Lose It! and others) With each occurrence I use the "Send Feedback" option provided within the Error Message. I've taken the usual steps - clear system cache partition, uninstall and then reinstall the affected application - but nothing seems to work. Is anyone else having this problem?
