A. Ensure that you are logged into the same account that you used to purchase the premium subscription. Sometimes, logging out and back in can refresh the app's memory of your subscription status. Check the account settings within the app to confirm your subscription status.

B. If the app continues to forget your subscription, try clearing the app's cache. Go to your device's settings, find the app under 'Apps', and select 'Storage'. From there, choose 'Clear Cache'. This can help reset any temporary issues.
