I am receiving the error above when trying to save the changes under 'Pricing and Availability' for a particular app on the App Store Connect web application. I have verified that this is the right data for the organization as it was taken from their Apple Business Manager enrollment information.
Is there another error or something I may not have done before trying to save these changes that I could be missing?

I just found the solution for me - I was using Chrome, tried everything (I was pulling apart network requests and everything).
Switching to Safari solved the issue.
