Gmail will no longer auto-sync/push on rooted S3
My rooted Verizon Galaxy S3 with Cleanrom Seven installed stopped automatically syncing my gmail. I can manually refresh my mail, but it does not sync automatically despite the sync being enabled. I've also wiped data, removed my google account, and even done a factory reset without restoring any google data...and although it occasionally works temporarily, it always stops working.
If a factory reset won't fix it, I don't know what to do anymore. Help?!?!?!
