In-App-Purchase Sandbox Test - Purchase not supported in your area
I am developing an application for Ukrainian people with In-App-Purchase. When I add a sandbox tester with Ukraine location and try to buy, I get this warning

If I use another place, Russia, for example, that's fine. My application is for the Ukrainian people, and it worries me.
Does anyone know how to fix this problem?

I suspect that since you are not entering an address but only a store, when you create a sandbox user, they don't know which region you are in and by default they block the purchase. In production, the user has a registered address that allows Apple to block purchases more selectively.
It looks like you will need to complete testing with a user from another store.
