Hi all! I might have found a way to create the link, I honestly don't know if it will work. So if somebody can try and confirm, would be great for all.
Luckily I saved my check in links before Airbnb removed the key icon. I still send them through the Airbnb chat to all my guests and they seem to be able to open. So I hope this works for you 🙂
I noticed all our Airbnbs have a code in the link, for example, the link to my property is:
https://www.airbnb.mx/rooms/28859000?source_impression_id=p3_1611249594_mIUzYDH%2B1wVIejuk
The code I refer to would be this number: 28859000
Now, my check in guide link when provided from Airbnb was as follows:
https://www.airbnb.com/reservation/check-in-guide/28859000
The code 28859000 is the same as the one contained in my property link, so maybe, if we put together https://www.airbnb.com/reservation/check-in-guide/ and add the code next, it could work.
If somebody does this and succeeds let me know!!
