"Add to calendar" not working on (Mac) desktop

www-zwift-com/eu/events/view/3271297

It works on mobile devices, probably since you’re sending the proper mime-type. However on desktop Safari, it just saves a file without extension. I’m only able to import it to the calendar after adding the extension “.ics”. If you would add the extension to the file on the website it would be easier to add it to the Mac’s calendar.

Cheers!
