Payment app issues with Firebase dynamic link

Hi,

We created a payment app that uses Firebase dynamic link for external redirection.

The issue is that if the client decided not to push through and went back to the merchant order page to select another payment method, the Complete order button is stuck in loading.

Did anyone experience this? How did you resolve it?

maybe similar to this?

No, it’s a different issue. We’re already past that, and our app is already approved.

This is the only issue we encountered as of now.
