Hi!
I’ve had that too except that in my case (I’m in the Netherlands), it doesn’t even say “short stay cleaning fees: 0€”,
it simply suggests to put a lower cleaning fee to attract more guests (see image attached).
I was also on the line with them just now and they refused to take responsibility. I would say, if anything, short stays are the ones for which you definitely want a cleaning fee!! It’s pretty much the same amount of work but for a smaller income…rather disruptive usually, but I keep offering shorter stays because I know sometimes one needs to book only one or two nights.
In any case, I have asked the support team to resend me the original email in which they informed me of the update. I am waiting for it…
