My Quickbooks subscription is not working despite it saying it is active and they have taken the money for the subscription.

Thanks for reaching out on the Community, @nwankwo-chizaram 

This error usually occurs when there is an error in communication between the billing on third-party accounts (Apple/Google Play) and QuickBooks.

I can see you have contacted our support team who will apply a fix for the issue. Please wait on a further email update to confirm once this has been applied. You'll then be able to access your account as usual - thanks!
