Welcome! Thanks for testing Resonance. When you tap to unlock the full version, Google will show a normal-looking payment screen with a real price on it. Don't worry, as a tester in this group you will NOT be charged. Look for the small "This is a test purchase" line near the button before you confirm. If it doesn't show right away, give it a few hours after joining this group before trying the purchase. Questions or bugs: reply here or email suninstalltech@gmail.com.
