Android 4.4 not backing up/syncing with google account
I have an issue with my device that since when I started trying 4.4 roms in general (I'm on CM11-m1 with gapps provided by cyanogen wiki atm) it doesn't sync or backup with the Google accounts I log in.
It doesn't sync my apps when I first install the ROM, it doesn't retrieve the WiFi networks that are saved in my account, etc...
I tried multiple ROMs, gapps, but no luck.
Stuff and can be marked to sync like GMail, Contacts, Chrome, etc, seems to be working fine.
One thing that I noticed is that Backup Account is greyed out (as you can see in attachment), and I can't get it to work properly.
Anyone knows anything that can help solve this issue?
