In the recent versions of Android OS Google has replaced its malware protection app "Google Verify Apps" by "Google Play Protect". The main goal of Google Play Protect is protection against various security threats such as malicious apps and OS security breaches. But it uses its own algorithms of machine learning.
Due to specificity of our app those priveleges and behavior of Addreality Player that are required to block sensor displays etc. are considered by those algorithms as malicious. We are already engaged in dialogue with the Google to add Addreality Player app into the whitelist, but unfortunately it is a complex and lengthy process.
To install the app in an error message saying "Blocked by Play Protect" select "Details" and then "Install anyway (unsafe)"
