Setting availability.

[Rob-and-Kathy0]

My calendar won't reset and change from blocked to available when I try to add available dates.

Did you cancel on a guest? If not try logging off then back on and see if that works. If you canceled on a guest ABNB won't allow you to re offer those dates.

@Rob-and-Kathy0  You don't mention how far out you are looking into your calendar, but if it is a few months out, your availability setting will be a factor.  Look at availabilty on the host bar and see how many months out you allow availability.
