I changed the minimum stay type and values disappeared. That's expected: switching Minimum Stay Settings clears the values of the type you stopped using. Run a full sync from your PMS, then check the Cockpit.
Same-day bookings stop too early (or too late). Check Cut off time and Cut off days under Property Settings. The cut-off uses the property's time zone, so check that's right too.
Dates far ahead are closed. Check Max Days Advance and Inventory Days under Property Settings. Availability closed with Max Days Advance doesn't reopen by itself.
The guest sees the wrong door code. Check the room's Smart Lock section: is the lock online, and is it set to the right door?
Turnover cleanings aren't being created. Open the room's Cleaning Settings and check the cleaning option, then the property's cleaning schedule (⋯ → Cleaning Settings on the Properties page). Check Cleanings Booked to see what's been created.
Invoices show the wrong company details. Update Property Settings → Invoice Settings for that property.
My Booking.com photos weren't imported. That's expected: Currently Elev8 imports listing photos from Airbnb only. Upload Booking.com photos yourself: open the property, go to Files, click + Add File, add a title and the image (JPG or PNG), and confirm with Add.
Invoices show tax I don't charge. Taxes on guest invoices come from the property's Fees & Taxes. Remove the tax there so future invoices are correct. To have an invoice already issued corrected, contact support.
An imported Airbnb listing is missing details. Airbnb doesn't hold everything Elev8 uses. Fill in the gaps in Property Informations, or run Autofill with AI.
