Playback of recordings - Device sensitive?

Browser sensitivity - the basic rule with BBB is “Use Firefox or Chrome”. But playback of a recorded session on a mobile device may be more sensitive than this.

Yesterday on an iPad I tried playing back my recording at Loading
Neither Firefox nor Safari would do this . . endlessly ‘loading’. While it’s ‘Loading’, the playback screen displays the Firefox/chrome notice in VERY small letters, almost unreadable. But Firefox failed anyway (uses the Safari engine under IOS?).

Should we post a notice for users of iPad? Other mobile devices? I suspect that our support for mobile devices in general is less solid than for desktop/laptops? If so, that’s serious. What’s the state of the Greenlight/BBB art on mobile operating systems? Can we assume Chrome-based browsers are ubiquitous on phones? Etc.
