I received this email from Google Playstore, saying that by 1 AUg 2019, a 64 bit app must be uploaded in addition to a 32 bit one.
https://android-developers.googleblog.com/2019/01/get-your-apps-ready-for-64-bit.html
I am informed that the Github for the custom app is 32 bit - when can we get the 64 bit app via Github?
