@Stephanie Same issue here with listings in El Salvador and support is running me in circles. I have submitted form W-8BEN. Now they say they are still withholding taxes because my payout is in USD. In El Salvador USD is the official currency. Another reply just said my listing are in the USA but they are not.
It's hopeful to read you were reimbursed!!! yays! could you please share more in detail what process did you do? I'm trying to help a friend that owns a couple Airbnb in Mexico. She's a Mexican Taxpayer. And has 0 business in USA, besides of doing the Airbnb, which they are in Mexico. She added her RFC to her listings. Airbnb has been withholding her 38% of her bookings. Also doing her facturing/invoicing (guests receipts) twice on the same 1 booking. Incredible confusing and very hurtful financially. She's unsure if filling the W8BEN would help her or not.
