"linked calendar" vs iCal link?

I’m on my iPhone app - when I go to one of my listings set with an iCal link to another, it says “no linked calendars”. Haven’t checked my PC yet, but does this mean I’ve lost my sync settings?

Yes, AirBnB is buggy again.

I see this too last few days, the calendars are still linked but not somehow not visible.

ICAL is a pain. I don’t understand why Airbnb and other vacation rental sites cannot use xml, which is much more reliable and in real time.

No problems on my iPhone with iCal
