This usually means Gust hasn't synced with Apple yet, or you're signed in to the wrong account. Try these steps in order.
1. Restore purchases
Open Gust.
Go to Profile → Settings.
Tap Restore Purchases.
Wait a few seconds. Most cases resolve here.
2. Confirm your Apple ID
Open the iPhone Settings app.
Tap your name → Media & Purchases.
Make sure the Apple ID listed is the same one that was charged.
If a different Apple ID shows up, tap it and sign in with the right one.
3. Confirm your Gust account
You sign in to Gust with Apple, Google, or email. Apple's charge unlocks Gust only for the Gust account it's linked to.
If you originally signed up with Apple but later signed in with email, you'll be on a separate Gust account that has no purchase. Sign out and sign back in with the original method.
4. Check your internet
Force-quit Gust and reopen it on a stable connection. The subscription check needs network access.
5. Wait 5 minutes
Apple's receipt validation can take a few minutes after a fresh purchase.
Still charged after all this?
Tap Contact Support in Settings and include:
The Apple ID email that was charged.
The Gust account email you're signed in with.
The Apple receipt number from your email confirmation.
We'll match the receipt to your account manually.
