As you know, MOD means editing APK files. As a result, the MOD APK files will not match the version available on the Google Play Store.
That's why Play Protect now warns you every time you want to install MOD APK.
So the best way is to turn off Play Protect completely and never mind it if you want to install and use the MOD APK.
Choose the version that has the
APK
or
APKs
or
XAPK
icon only if you want to download the original.
Choose the version that has the
MOD
icon if you want to download the MOD version.
