I must pay again

[kandalog]

I upgraded my plan on June 11th.
At that time, the credit card is registered as a subscription
So I downgraded. To cancel the credit card linkage
I thought I could use it for a month even if I downgraded
However, it could not be used.
So. I try to upgrade again. Then I must pay again.
Why?
I paid $ 6 for 3 minutes

The payment behavior is handled via Stripe. AFAIK, the extra paid fee should be deducted from the next subscription cycle. Please check this to learn more. https://stripe.com/docs/billing/subscriptions/prorations
