I wasn't even aware that there were "Business" and "Education" versions of the Microsoft App Store.
Note, the "Windows 10" version of the store does not require a zero price.
So I looked and there were a couple of my Apps in the "Business" and "Education" stores. I have had these Apps in the "Windows 10" store for years. And they remain in the "Windows 10" store with non-zero prices.
As far as I know my income from the "Business" and "Education" stores is zero, so I'm not going to miss them.
I am planning on being completely out of the App Store business by the end of the year, so I'm not worried about it.
For iOS Apps with Apple, they do ask if I would be willing to allow them to use the Education Discount for my Apps. I believe I have always been willing to let them give the Education discount, I can't remember if I have actually given that discount to anyone.
