Hello, I am having a problem syncing my Gmail contacts after doing a factory reset on my GS7. The contact name, number, and email all sync up fine. But the group classifications are gone, each of my contacts are assigned to a group. For refrence, I have the same account/contact list on my business phone (note 4) and the group assignments are still correct. On my desktop these groups have also been stripped off at some point. This has had to occur recently because I switch devices every month or so, and this is the first problem syncing. So I have to assume my business phone (note 4) is the problem. Under settings I'm not seeing any sync errors at all on either device. Any advice?
