modify reservation

[Arm-and-Alex0]

hi, i'm tring to reduce the price of the rent for tenants, at the last stage, i'm sending the request and it says : "error, contact host assistance " - "Une erreur s'est produite ! Veuillez contacter l'assistance utilisateurs pour obtenir de l'aide" - which doesn't exist as there's no assistance. No idea what the mistake is about...

If the check in is within 24 hours, the reservation cannot be changed without contacting Air BNB.  Perhaps that is the problem
