It worked well initially, so I’m sure that the recent changes I did on this phone caused the issue. Whenever I remember or expect emails on Gmail, I had to open it and refresh manually to get new emails.
But that is weird when you have a smart phone with proper email client and internet connection always.
This fix requires no action, and will roll out globally over the next week.
Two weeks ago, Gmail 5.10 rolled out but the updated app only fixed synchronization for Hotmail accounts, not other types and most importantly, not Gmail accounts.
At the time, we knew that the more pervasive sync bug had been identified by the team, but that the fix hadn't been implemented yet.
I have a Samsung Galaxy S3 and I love the new Gmail app. My only problem is that it doesn't sync emails (I don't receive any new notifications when new emails arrive, I have to manually click refresh in the app which is annoying) when I'm on Mobile Data.
When I'm on Wifi I receive notifications almost instantly.
