Hi @Chris12935 I hope you are well!
Switching primary hosts isn’t an issue, as that isn’t related to the ownership of the listing/account or back end financials.
Unfortunately it’s not possible to change the listing admin, which is why you’re running into difficulties.
Really you need to create a new listing under your own account, you’ll then be the listing admin and will have full control over payout methods, co-hosts and so on.
Could be more tricky if there are future live bookings on the original listing, in which case you might need some assistance from Airbnb.
