I had intermittent issues before with my Google syncing not working as it should (although I've always been able to go to google.com in the browser), rebooting usually solved it. However, after upgrading from an older 10.2 version to the latest one (via CMs own update functionality), both the Wifi icon and the mobile data icon stay completely grey. As usual, I have no issues with going to Google in the browser, so I'm suspecting this is a Gapps issue or something with the ROM.
Any ideas on what I can do to troubleshoot and/or solve this? I'll go ahead and try upgrading Gapps now and let you know how it goes.
This is not a duplicate with any question asking what this greyed out icon means, I'm asking specifically why the sync functionality stopped working with the upgrade (if anyone knows), and how to fix it (if possible).
edit I just realized I might be running 10.1 gapps on a 10.2 CM build, I'll update this if upgrading gapps solved the issue.
