Hi! I understand you had a lifetime premium membership on Sticker GO! after participating in the special reward program, but it disappeared after the first update. Let's get this sorted out together.

First, just to confirm:
- Are you signed in with the same account you used when you got the lifetime premium?
- Have you tried the “Restore Purchase” option in the app yet?

Here's a simple step-by-step you can try to restore your premium status:
1. Open the Sticker GO! app on your Windows device running WebKit.
2. Go to your profile or settings area (usually represented with a gear icon).
3. Look for an option labeled “Remove Ads” or “Restore Purchase.”
4. Tap on “Restore Purchase” — this should reconnect your app with your premium status on the server.

Sometimes after updates, the app needs a manual refresh of your account features like premium benefits. If you haven’t tried this step, it often resolves the problem.

If that doesn’t work, please let me know if you notice any error messages or if anything is different after the update. Also, how did you receive the lifetime premium—was it directly in the app, via a promo code, or through a third party?

I’m here to help! Let’s try this first and take it from there. For more details, you can also check the official restore guide here: Restore premium account - Sticker GO!

Are you able to see the restore option in your settings?
