I bought Minecraft for windows 10. I paid immediately, which all worked out. But the purchase is not shown in my order history and when I click on Minecraft in the Microsoft Store again it just says "buy". Do I just have to wait a little or can I forget the money (what was withdrawn from me)?
As long as you can prove that you paid and got nothing, nothing is lost. I would suggest if you have not received it tomorrow that you just contact the support that can surely help you.
