Is anyone else seeing this in messages from inquiries?

I haven’t noticed this. A few months ago I have a couple of enquiries come through the Airbnb app on iPhone which said “unsupported attachment” and some of the time there was no attachment at all and another time the guests selected a check in window which I found out by logging onto my laptop.
Is that the type of message you’re getting?

Is anyone seeing what, exactly? More details, please.
