Windows 10: Unable to redownload a purchased game after it was delisted

I previously purchased the Microsoft Studios published version of Zombies!!! for Windows 8. I have it installed on one of my Windows 10 machines, and it works fine. I went to install it on another Windows 10 machine, and found it's no longer even in the Microsoft Store app. I've looked through my purchase history on the website and can find it, but it's not listed in my purchase history in the app. Does this mean I will not be able to reinstall it on any future computers? If not, is there a way to copy it from one computer to another? I wasn't aware that digital purchases would be removed at s

Delisted games on Windows Phone 7/8

There is not enough games to even delist. This is not how showing your supporter support please get this straightened out. I want those games and not refund I hope enough user voice their frustration so there is a good explaination for this delist practice
when there is no easy way to backup your purchased.

 

I am unable to redownload a game I previously purchased

I previously purchased Forza Horizon 3 about a year and a half ago or so, or upon release...

For some reason I am unable to redownload it... I can see it in my order history although when I view it in Microsoft Store I am asked to purchase.

 

Unable to redownload an already purchased app

I am unable to redownload an already purchased app (thumba). I bought the app on my Lumia 610 and now I'm trying to download it on my new Lumia 800, but Marketplace is wanting me to buy it again. Also Zune doesn't say I've purchased it either.
