App Sharing

This is what Google AI had to say:

Yes, Walkabout Mini Golf VR supports Meta's App Sharing feature, allowing multiple players to enjoy the game on different headsets using one purchased copy. To enable this, one headset must be set as the "primary" headset under the main Meta account, and a secondary account must be created on that same headset. On the second headset, the secondary account is used, with App Sharing enabled on the primary headset to share the game. 

Here's how to set it up for simultaneous multiplayer use:
Designate a Primary Headset: Choose one headset to be the "primary" device for the owner's main Meta account. 
Create a Secondary Account: On the primary headset, add a new secondary account for the other player. 

Enable App Sharing: On the primary headset, go to settings and enable App Sharing, allowing all secondary accounts on that headset to access the primary account's purchased apps, including Walkabout Mini Golf. 

Log in on the Second Headset: Log into the secondary account on the second headset. 

Create In-Game Profiles: For Walkabout Mini Golf, it's recommended to create a new in-game profile for the secondary account to use. This allows both players to launch and play the game simultaneously. 

Important Considerations:

No Simultaneous Logins on the Same Account:
You cannot be logged into the same primary account on two headsets simultaneously and play the game at the same time. Attempting to do so will result in an error message. 

In-Game Profile Names:
Using the same name for both players will lead to confusion in the in-game scoreboards, so distinct in-game profiles are recommended. 

Guest Passes:
The game also supports a guest pass feature, allowing players who have not purchased specific courses to play them with a friend who has. 

Yeah that did cross my mind, might give that a go thank you
