Your was very keen to update android 7 on BV8000pro every month, but with Android 8 northing happening for 9 month.
Google has relist a lot of updates at the same time.

Why have you not bothered to update android 8?

Because, as stated many times in many threads, tech team set the maximum priority on fixing ROM issues in many new other phone models. Development on BV8000 hasn't been stopped, but slowed a lot.
