I'm facing this same issue, did you ever figure out a solution? My problem is I'm using the new smart lock integration which auto-generates codes, but my "How to get inside" info says it's the last four digits of their phone number. I can't find out how to edit this info anywhere and I need to remove it.
EDIT: Figured it out!
I was able to edit "Additional Details (optional)" in the Check-in method section. This info seems to overwrite whatever was there previously. In my case I had a smart lock as my check-in method, so I'm not sure if this will work for everybody.
Follow these instructions (works on the app or web browser):
- Go to the listing editor
- Click on Arrival guide
- Click on Check-in method
- Click on Additional details
- Put some instructions in there and save
- Check the preview to confirm the "How to get inside" details were changed
You can also delete the additional details and it should just remove that section entirely, just need to overwrite it first!
