Hi Michelle
Im not sure if you already had some feedback on this topic but the way I see it is as follows:
You can setup your payments to be split between different payment methods for example:
50% could goto your Payoneer Debit card, this will be done in USD as thats the currency that they work in.
50% could be via bank transfer, I noticed that this is also handled by Payoneer which i guess AIRBNB must be using when that change came in a few months ago. This payment will be sent to your local south african bank account and will arrive in ZAR.
Hope that clears up some of your questions.
