A pre-approval is different from a pending reservation. I have had pre-approvals stay for weeks on my account. Its usually when someone sends out inquiries to several hosts and then makes a decision out of the several options. Generally, people will not respond to let hosts know they chose something else. Its not a big deal but it would be courteous to let a host know a yes or no and not a lingering maybe...
A pending reservation is the one where a potential guest has decided they want to make a reservation, payment info has been submitted, all that is waiting is final approval from host to be accepted. This is the one that expires after 24 hours not a pre-approval to an inquiry.?
I have the same problem since there is no button to remove pre-approval. Is there another way to do this
