User paid for subscription but is not shown in RevenueCat

Hi!

I have an iOS user that paid for an annual subscription. I cannot find her as a paid user in RevenueCat, given that situation, she was asked by the app to pay again and she paid for a monthly subscription.

She now has two active subscriptions but none of them are recorded by RevenueCat and she cannot still access the paid features in the app.

I don’t know how to proceed because that’s the first time this happens to us with RevenueCat. Any help will be greatly appreciated.
