Don't make your life difficult guys.
You can live without gapps as well.
I have setup my p40 pro without gapps and everything works fine.
Nine mail instead of Gmail, tubemate or browser instead of YouTube, apkpure instead of play store, Firefox ...
Tested and working perfectly on mine : https://www.youtube.com/watch?v=B6LCjatk3ys
Actually works with every method but always have the annoying notifications about certified device. I turn off all notifications on these apps and now i am OK.
I have install chat partner full apk again and run it once more. He ask me to Uninstall Google services and continue with setup. After finish setup, restart the phone and everything seems good again.
oh my god....what shes doing?????????
