Hi Jamie,
If your wife, as a co-host, can't see the guidebook you've created, it might be due to her permission level. For her to access and view the guidebook, she’ll need to have "Full Access" permissions.
This setting lets co-hosts see all listing details, including any guidebooks you’ve created.
To adjust her permissions, go to your listing’s settings on Airbnb, find the Co-Hosts section, and ensure her permissions are set to Full Access. This change should allow her to view and edit the guidebook.
I hope this helps.
All the best,
Upfish Management
