FYI - take the ABB survey that is repeatedly sent out to hosts via emails and suggest they make that visible. That's what I just did last night regarding this VERY issue. They are a very receptive company and need to make improvements as they grow. They do that with the help of hosts letting them know what we need. And I took the survey and write specifically about the rate especially bc I'm now getting Instant Booked by guests w 5 Star reviews only. Hope that helped a little getting a reply back from me.
Another thing, you can always look at the guests booking breakdown invoice which is also emailed to every host to see what they were charged nightly as a tool but it's not exact.
If you feel that me or another host have helped you, feel free to click on the "thumbs up" button at the end of any post. Thank you so much.
