Limited African Countries On The Webstore

Why are there a few countries in the fc mobile webstore especially Africa because i see there only 5 countries that is :

-Egypt

-Kenya

-Morocco

-Nigeria

-South Africa

So i was implementing that they add more African countries because we the players we don't only come from these countries like me, I come from Uganda and i don't have the ability to pay on the site so i was saying that addition of other countries will be a great improvement. Thank you
