Hiy Guys
Device MI4
Rom 4.12.26

I have read a lots of threads about notification delay on MIUI but i cant find nowhere a solution for this bug. I talking about the stock email app, not whatsapp, hangouts etc. There is a push notification bug when using mobile data. I have teste this a few times. Emails comes in with delay between 5 and 30 minutes. As business user its a very strange bug. So guys did you have the same problems with stock email app and push notification. Is there no solution for this bug?
