Not sure if anyone else is having this problem but I do not seem to be getting notifications for each of my Gmail accounts since upgrading to 4.4.2. I have checked the account settings and each one has the notifications box checked but I often (multiple times per day) go into the accounts and find new mail even though no notification was present. I do receive notifications but I believe that they are tied to only one of my 3 accounts. Anyone else have this problem and been able to find a solution? Thanks!
