I don't offer anything other than the Self-Check-in Instructions which all guests have access to.
Under Check-In-Method I selected "other" I then have it say-Guests will be using the App Integrated Self-Check-In Instructions, contact Airbnb Support if you need help locating them.
I found if I simply put my lockbox code guests used the code and never attempted to find the actual Self-Check-In Instructions.
I am a very hands off host. I still maintain 5 stars with my direct approach of directing all guests to contact Airbnb Support if they can't navigate the platform.
I can't spend time offering different ways for guests to receive information. By creating links, PDFs, emailing, sending messages pertaining to guests requests for check-in instructions Airbnb will never truly know how hard guests struggle to find instructions.
I want my guests contacting Airbnb if they can't find instructions. That's how Apps get better.
