background data restricted, no matter if i choose to restrict background data in setting or not. nexus 5 kitkat and/or lollipop same thing. it practically gives you one option: quit
sometime a restart helps, but only untill i install a new app.
same problem when i had the kitkat crap or lollipop 5 or 5.1
Welcome to Android Central! How can you tell your background data is being restricted?
Also, bear in mind that it's possible to restrict background data for a specific app, rather than doing it universally. Is it possible that one or two specific apps have their background data restricted?
