Hello @Lisa8619
I'm a cohost and would never set up a listing under my profile as the main host.
The listing should have been set up under your profile with the cohost added as a cohost. This is so that you get the reviews and ratings and if you no longer want to work with the cohost you can manage things yourself or get a new cohost without losing all your reviews and ratings .
1 As the cohost you are paying to advise you should have told you - you will lose all your reviews if you change the listing for it to be under your name
2. yes of course you can pay the cohost whatever you want but why do you want to double what you pay them?
as you can see both your listings are getting what airbnb sees as very low reviews for key areas like cleaning and accuracy . What is your cohost doing to work with you to address these issues that guests have complained of?
Personally I would start again under your own profile .
