Rivo 5.3.1

Installs as an update over any earlier version. Requires Android 8.0 (API 26) or newer.

Signed with the same key as 4.1.0, so this installs over it and keeps your history, rules and settings.

The paid tier does not unlock in this build. It was compiled before a Play licensing key was configured, so in-app verification fails closed and the app stays on the free tier. A build with licensing is coming once the Play developer account is active.
