I just notice that the following error when the form is submitted:
Submitted value ($0.00) does not match expected value ($XX.XX).
The form had worked previously without any issues, but today a customer shared a screenshot with this error when trying to submit payment.
Any ideas why this would be happening would be greatly appreciated.
If you are running 2.9.0, try updating to the latest build, available from your support account, which includes a fix for an issue where the total does not update in some scenarios.
