My Galaxy S3 updated to Kitkat the other day, and I noticed that anything related to Google stopped syncing, mainly my gmail and contacts. The last time I had a problem I just removed my Gmail account and re-added it, so I tried doing that again. The problem now is that It won't let me re-add my account, it jst gets stuck in a loop of asking if it's a New or Existing account. Is there anything else I can do before resorting to a factory reset?
