How to handle guests that don't respond within 24 hours to an initial booking request

She didn’t respond to anything, but cancelled the old request, and made a new request. I responded with - you still need to reply to me. So far she hasn’t - it’s been a few hours. I’m considering whether to decline; people with poor communication skills don’t usually improve on further acquaintance.

To be honest, I wonder if the AirBnB message system has a (big) problem.
Last few days I had several guests not responding to questions, only after I rejected the booking they suddenly responded, saying they never saw the message.

In the past I never had this problem, but now it seems that the message system is not working properly.
