========================================
After updating to A11 I started to see major issues with the battery optimizations, mostly on Gmail app, but once I started to investigate I see it overall. Email notification come with hours , if not tens of hours delay , which was not the case on A10. I noticed that even whether app is not updating in timely fashion.
It looks like phone goes to hibernate and not resumes for notification only once in a couple of hours if not more. Strangely but whatsapp is working fine. I have disabled all battery optimizations and I saw some improvements but not that good as in A10. Yesterday for instance, I lost a couple of important emails since they Gmail App only synchronized once in 10 hours....which is unacceptable.
Factory reset does not help since I have done it at least 7 times due to various issues since A11 update a week ago...
Please help!!!! I don't know what else to look for!
