I too have this question. I thought that accepting reservations was automatic. I don't see a place where I actually accept or reject a reservation- so I'm confused.
The reason that I'm asking about this is because on the mobile app I was directed to a page called Basic Requirements. I have 2 requirements (that it tells me needs my action.) One is overall rating. And I understand that will come after someone stays. The 2nd requirment is accepted reservations. The description says, 'make guests feel welcome by accepting requests whenver you're available.' The target is 88%. I have absolutely no idea how to achieve that target.
