This is a global bug (in china roms - xiaomi.eu) apps: whatsapp,gmail,GG,Telegram.Maybe can you download and check? Each phone is different. There may be a problem in one model, not the other.
Note: The update for Mi MIX 2 and Mi 6 is suspended due to interface FC issue that may occur sometimes.
FC on china assistant.. so no issue for us..MIUI China 9 Android Oreo for Mi Max 2 and Mi6 Suspended!
Bugs! If You install Xiaomi.eu 8.1.18 for Mi6 or Mi Max 2 you have to count on bug.
Why does Xiaomi.eu issue roms like Miui China 8.1.11 and 8.1.18 suspended for these phones?
double app notification icon in status bar when first message arrives is fixed, but disappearing notification when second message arrives still there...partially fixed so at least one step forward...the problem of the double notifications that disappear has been solved? there is no more written between the known problems.
That should be here: Settings > Lock screen and password > SleepI opened a thread on bugs section also, in settings / display / display sleep time cant be changed . Anyone noticed ? Thanks.
Thanks for help, i didnt know this settings exist here, and worked with this settings. Changed and worked. Miui optimiziation is closed on my phone.That should be here: Settings > Lock screen and password > Sleep
It seems you are using same tweaks or modding or you turned off MIUI optimization in developer options
