Beta testers outside the US, for our MacOS App, are being told their ID is not valid in the US Store and that they must switch to a store in their country. Yet the store switch fails Essentially beta testers outside the US cannot do testflight sandbox eCommerce for the Mac version of our app. Note that eCommerce on the Mac works for US based testers and eCommerce for the iOS/iPadOS works for testers in all territories. Many of these testers are in India, the UK and Canada. We believe that this is incorrect, that storeKit is not correctly detecting the AppStore Region for mac based testflight eCommerce. At this point we have 382 testers, most outside the US and we can only Beta Test our app with US users. Attached are images of the messages that are coming from storeKit: Here is a link to a video from a user in Canada who is demonstrating the problem (cut and paste into browser) https://youtu.be/kB818wfVld4 Here is another link to a video from a user in Canada who is demonstrating the problem (cut and paste into browser). https://youtu.be/7uAZKo8wpfU We see that there is another post with a similar problem. Similar eCommerce Problem Because eCommerce works in all territories on iOS/iPadOS but ONLY in the US for Mac we suspect that this is an error that either a DBA or a coder will need to fix. Any insights from anyone would be appreciated.
