Payment failure at Google Appsheet

I am trying to Upgrade to App Sheet starter secure plan.

On entering all details (including Credit Card) it throws the following messages: 1. Please see ‘App Info Plane’ (https://www.appsheet.com/account/account/AppInfo) . Not useful it shows the same things.

  1. https://stripe.com/docs/billing/subscriptions/overview#requires-action. No information here. All information here is for the Google Engineers who are using strip services and have delopment stripe for payment collection.

When I entered credit card details it did not ask for any OTP, etc. Credit Card is enabled for Dollar payment.

Any help will be appreciated.
