Tax changing AFTER customer completes payment

Well, I will add my issue to the pot. On top of similar issues to those mentioned. I have built an API integration that captures the information. As we have multiple locations and multiple storefronts, both physical and online. Fortunately, I am a good developer, and so I accounted for a mistake like this possibly occurring. Otherwise, our books would have been off. But even so, now I have to go manually calculate and change something that I built an automation for. And why? Because Shopify developers made a mistake and have not fixed it yet? I guess not enough people complain. I hope they fix this soon, it is troublesome to be sure. And costing my dev team valuable time.
