@Ben-and-Sam0 Haven't read any thing but what was stated in the article. And supposedly it isn't an option yet in North America.
It seems to me that this is just a ploy to get hosts with Strict policies to switch to Flexible or Moderate. An also unfair to hosts who have always had a flexible or moderate policy, if they are going to boost the "switchers" in the rankings over those. I'm sure Airbnb is having a really fun time right now fielding phone calls from irate guests screaming about getting a 100% refund due to coronavirus, even if they aren't in or going to an affected area.
