It's not that simple and yes Airbnb support has really deteriorated to horrible Orwellian levels.
We have some properties that require an in person greeter check-in. One out of every 500 guests does not respond to our repeated Airbnb messages, text messages or voicemails and just shows up at the property. When they realize that they don't know how to check in, they contact Airbnb support and we get one of these nasty templated messages: "you have 30 minutes to respond or else!"
The support ambassadors (who are often overseas in some overworked, underpaid call center) don't even bother to read the messages which would clearly show that we have been trying to reach the guest for days.
Similarly, for properties that have a self check-in entry code, if the guest cannot input the code correctly to enter the property, Airbnb support would still send you the same "respond within 30 minutes" threatening message even though the entry instructions have been provided to the guest.
A reasonable person might expect Airbnb support to consider the timezone that the host lives in or the timezone of the property. That is not the case. We get calls from Airbnb support after midnight, on weekends, or as early as 5am-6am.
Basically, Airbnb does not give a **care** about its hosts any more.
