For the notification problem of the xiaomi phones, we can only solve it step by step. It happens to many china phones even with the global version. That's stupid but we have no ultimate solution indeed.
I try to solve it with a very stupid method everytime I flashed the rom.
1. Turn on battery saver globally.
2. Then on saver for those apps.
3. Turn off saver for those Apps.
4. Turn off savee globally.
5. Turn off notifications for those apps.
6. Turn on notifications for those apps.
7. Reboot
Stupid enough?
