In a steam family, my wife sees my games I don't see hers

[-=> Indy <=-]

My wife can play my games but I can't play hers, why?

Her games are Kingdom Come Deliverance and Inzoi

You have to manually add Steam Family shared games to GeForce Now.

GeForce Now Integration:
You can play Steam games shared through Steam Families on GeForce Now, a cloud gaming service, by syncing your Steam account with GeForce Now.
How to Play Steam Family Shared Games on GeForce Now:

Sync Steam Account: Go to GeForce Now app > Settings > Game Sync and press the Resync button to sync your Steam account.

Mark Game as Owned: Manually search for the game on GeForce Now, mark it as "owned" on Steam, skip the sync in the prompt that follows, and then confirm when it asks whether you really own it.
Launch Game: The game will then launch and run fine, and also appear in the GeForce Now library.

Yay, that worked! I kept syncing instead. Thanks for the fix!!
