The Google servers that process in-app subscription purchases and renewals occasionally approve a transaction but fail to notify SCRUFF. If this happens when you purchase a Pro feature (or when your subscription renews), the subscription feature may not be enabled (or may appear to have expired) in SCRUFF. If this is the case, you can restore your Google Play subscription provided you have an active subscription with Google Play.
