Welcome to the Community, @seaklearpools. I want to make sure this is taken care of immediately so you can get back to business.
To clarify, as soon as your billing is updated, you should be able to get back with using the product. I'd recommend contacting the Apple Support Team to verify the payment. They can help you take a look into your account and ensure it's activated on their end.
You also want to consider uninstalling and reinstall it if you encounter the same issue.
Here's an article you can use to update payment information through Apple Billing: Update your payment information with Apple Billing.
