According to the linked support page, nothing except Apple OSes and Windows is supported; not even desktop Linux! That's quite an accomplishment in 2024. They really went above and beyond in not supporting any modern browser.
Interestingly that /abc link works for me on Linux (Brave), but the published link doesn't work for me on Linux+any browser, Chrome included.
Agreed, quite annoying. I own a bunch of Apple stuff, but when they do this crap i can't invest further into their ecosystem because it's unusable to me much of the time.
