Asus Max Pro M1 android 10 update case is similar to Moto G4 plus android Oreo update cinerio. Don't blame asus .every company does this regarding 2 nd major Os update to old phone. I have Moto G4 plus also in my family..Oreo update came for this phone in July 2019.which is very very late .At that time android 10 developer previews are going on pixel devices.and that time after 1 and half years wait Users get Oreo update and software support ended with this update.
Don't compare useless Chinese ui phones with stock android phones..Miui , color os, realme Ui etc are not as good as stock Google Android Ui..Every company providing this stock android Ui is struggling to give major Os update to their phones..
Also there are only 2-3 best companies are remaining there in market that provides stock android Ui like MOTO , Asus Max series ,Nokia etc..The only reason they develop their own Ui is that they are not capable to give users stock Google Android Ui interface updates..So, for our Max Pro M1 device , android 10 stable will arrive definitely don't worry abt this.Probably will arrive in next month , and also with this update our software support will end finally.
Remember this is not a android one phone like Nokia phones..still asus manages to provide security and os updates support since last 2 and half years..So keep patience , android 10 will definitely arrive bcz asus promised in promotion that it will get 2 major os updates..It is exactly the same case like Moto G4 plus android Oreo update..
