Do you know if the Pro edition of Firewall Android I purchased is active?
Are you wondering whether the Pro edition of Firewall AI Android that you purchased is active? If you purchased it from the Google Play Store, it should be automatically activated without requiring a license key.
To confirm if the Pro features are enabled, please go to the settings and check if you see "Firewall PRO" at the top. If you do see it, then all the Pro features are already activated. If you don't see it, please try restarting your device and checking again.
