Upgrade not available in French Store

Hi–

I live in France. I bought Task Paper here. I’ve just upgraded to OS sierra, and my old version doesn’t work. When I go to the app store, I’m told that its not available in the French store.

I’m stuck alors, What do I do ?

Is anybody else from France seeing this problem. TaskPaper 3 should be in the French Mac App Store I think. At least it shows up for me when I change the language setting in my own Mac App Store. TaskPaper 2 did get removed from all app stores, but TaskPaper 3 should be there. When you search for “TaskPaper” you don’t see anything?
