Why gears of war 4 game can't download from microsoft store, is there any problem?

I’m about to download gears of war 4 because I just finished the first part. But when loading to play It can’t be downloaded from the microsoft store even though we bought it. Is it a problem?

someone else finally has my issue

The ability of downloading XBox games are removed from Microsoft Store. Instead you can download them from the official XBox application.
Worry not… You don’t need to rebuy everything from XBox if you had already bought them from Microsoft Store previously.

And in case of Gears 5, only the base game can be downloaded from the XBox app. Multiplayer, Costumization, etc… can only be installed from the game itself.
