Missing Some App Notifications On Mi4c

Oct 27, 2015
Guys i have the latest multi eu (14 february), but after a few months i have the mi4c i still don't receive notifications by some apps.
For example: even if i set auto-start and access to internet for Telegram i don't receive anything until i open it. The same happens for Inbox and Gmail or Tapatalk or Reddit!
Please do you have any advice?
