I made several reservations yesterday. Today I went to add them to my calendar and the function seems to have changed or is broken.

I use and external web calendar system. In the past the "Add to Calendar" downloaded an .ics file which I could import into my web program. Yesterday I tired to do that and nothing happens, I get an little box popping up under the link but nothing else. I've tried different browsers (Chrome, Chromium, Brave, SeaMonkey and Edge) on two different computers in different places (one at my office and one at my home) running different operating system (Windows 10 and Linux). I typically go to "My Account" then to "My Upcoming Trips" open the "Details" and select 'Add to Calendar"

Anybody else seen this/
