Luv your 2 properties!
Hmmm...this is very strange. I just went in as a guest on both your properties and it showed that I could instant book and make a reservation (not request to book).
Guest Searches
Remember, if a guest is logged in on Airbnb and you have selected the optional instant book option of no negative reviews (or If a guest doesn't have any reviews; new to Airbnb), then the property will not show up in search results for them if they choose Instant Book as a filter (I believe). This could be what is happening. Check and see if you have optional instant book settings ON:
The way to verify this is try searching as a guest, without being logged in to your profile (do an incognito search not logged in). See if the properties appear with the instant book filter ON/OFF. They should appear. You could have someone (a friend) who doesn't have any past bookings on Airbnb, but has an Airbnb account, do a search. If they select instant book as a filter, but don't have any reviews (new) then the properties should not appear (supposedly - Airbnb had a problem with this feature for awhile).
You should receive a request to book on any guests that don't have reviews. You get a request to book with the callout below appearing:
Some other things to try:
1. Try toggling Instant Book OFF, then back ON on a
computer/laptop
2. Try toggling Instant Book OFF, then back ON on your mobile
phone
Let us know here if you are able to resolve it as other Hosts might be having a similar issue.
