How to download from Google Play without Wi-Fi setup ? I always got "waiting for wifi" when tried to install apps using mobile data.
Untick download using Wi-Fi doesn't help. BTW, I'm using MIUI 9.5 Chinese stable.
I downloaded then install the latest version of Google Play Store from APKMirror, After the installation, the problem is gone!
However, I still don't know why Playstore couldn't update itself.
Go to Play Store-> Settings -> App Download Preference and select 'Over any network'
