Just tap OK the dialog that says “This app was built for an older version of Android….” when opened for the first time. If OK button is not visible, just tap the blank space on the lowest portion of the dialog.

If Google Play Protect will prompt during install that the app is built for older version of android and doesn’t include the latest privacy protections, you can ignore it and proceed to the installation. For privacy related concern, please refer to FAQ No. 3.
