First, check your Subscription tab — if you see more than one active plan, that's likely the cause.
Contact support with your billing email and specify which plan to keep. We'll cancel the duplicate and refund the extra charge.
Common causes:
Clicking subscribe multiple times. If the page didn't confirm your purchase right away and you clicked again, each click may have created a separate subscription.
Subscribing through multiple platforms. If you subscribed through the AppStore and also through the website, those are two independent subscriptions — each charges separately.
Unpaid invoice reactivation. Purchasing a new subscription with a different card while an earlier unpaid invoice exists. Once card details update, the system charges the missing amount and reactivates the previous plan.
Seeing a free plan and resubscribing. Logging in with the wrong email shows a free plan, which may prompt an unnecessary second purchase. Check that you're signed in with the email you originally subscribed with.
If you see a failed payment banner, do not buy a new subscription — use the resubscribe button on that banner instead.
