I paid for Windy one year today, and I can't find Windy even if I go to the "Payment & Subscription" menu of the Google Play Store to cancel in case I forgot and made an incorrect payment.

I also found out for the first time, but when a user makes a payment by adding Google Play Points, the product list does not appear in the "Payments&Subscriptions" menu, and we have to contact the payment developer directly to cancel. Google made it very strange.

Windy should be aware of this. Anyway, I would like to cancel the payment, but I am unable to cancel the subscription directly through the Google Play Store. How can I do this?
