Any successful stories on making money in Windows app store?

Anyone making any worthwhile money as a solo developer in Windows app store? https://www.microsoft.com/en-US/store/apps

What's your app and how much are making every month?

I am also reading about negative stories about the store and I am not sure this is true these days. https://betanews.com/2016/01/22/developer-windows-store-is-a-disaster/
