I'm not Chinese either, but get along in the language well enough.I realise that We Chat, despite being able to converse in English would essentially be an Asian centric App. I still can't figure out why I have been locked out though.
I was thinking of purchasing a P20 pro for its camera functions mainly and was wondering whether the current Android OS could be swapped out for 'Hong Meng 'when it's released, or simply wait for the P30 series running Hong Meng.

On WeChat I have the 2factor set to my cell phone, not email. But unfortunately, cannot help you there.
For the Google Maps alternative, use Baidu Maps.
