I am so sorry about that. Airbnb is currently engaging in quite a bit of unethical business practice at the moment in effort to reabsorb some money. I just posted this in the forum:
"A number of Superhosts have travel coupons set to expire on July 1, 2020. Airbnb is refusing to extend the expiration date or offer a new coupon and instead is "encouraging" Superhosts to travel. In some cases, such as mine, this would go against state orders. In nearly all cases, this forces Superhosts to make a choice between getting to use the coupon they earned and ensuring their personal safety. Both cases are unethical. I have heard from someone in the main office that the reason Airbnb is doing this is so that they can reabsorb that money. If you cannot travel and/or do not feel safe, at least support another host, perhaps a stranger, and book a stay even if you won't actually stay. Don't let Airbnb take advantage of its Superhosts!"
