Gmail syncing issues

For about 3 weeks my phone has refused to receive emails. I have done no firmware or factory updates of any kind.

If I open the power control, it has the sync turned on. If I look at my accounts, it should be syncing my contacts, email, and calendar. It is doing none of that. If I click sync now, nothing happens. If I open the Gmail app and try to manually refresh, nothing happens.

I am stumped. I don't really wanna do a factory reset so any suggestions would be greatly appreciated.

 

Thanks! Also restarted my phone and it seems to have fixed it. It also seemed like my gmail app was putting everything in Spam since I had 51 junk emails on the app and zero on actual gmail.
