Two charges for Pro usually mean two live subscriptions from different places, most often one through our website and one through the App Store or Google Play. They don't merge or cancel each other out, so you keep paying for both until one is stopped. Here's how we sort it out together:
Tell us through Settings > Contact Support in the app. We will refund the website charge on our end.
Cancel the store subscription yourself, since we can't do that for you: on iPhone, go to Settings > [your name] > Subscriptions > 1SE > Cancel Subscription; on Android, follow the steps to cancel on Google Play. Pro stays active until that subscription's period ends.
Once it has expired, subscribe again at me.1se.co/pro if you'd like to be billed by us.
If Pro looks missing afterward, sign out of 1SE and back in: that refreshes a website subscription, while Restore Purchases only picks up store subscriptions. A brand-new Google Play subscription may not show on our side until its first payment goes through.
