The same story here in Prague, Czech Republic.
We are the last year Airbnb best selling experience here, had the most 5star reviews, earned Airbnb sooo much money on commissions and we have been declined. Posted the experience in June 2020.
Than we really pushed and they told us that it was a mistake to decline us, and we are approved. BUT we are on waiting list - and after about 30 emails, phone calls to USA they told us that they are missing some "new approval tool for online experiences" and it would be ready at the end of 2020.
Now new online tours are being added, no call or message from Airbnb - NOTHING .
We are super disappointed by their approach and that there is no actual email address or person where to even ask questions.
Always persuading some random guy on hotline to reconnect you somewhere.
If you had any relevant Airbnb contact we are all ears (we would even fly to the States if not COVID sh..).
