However PDF should still work on all platforms because:

Windows & Linux are CEF (Chromium)
Mac is WebView (WebKit based)
iOS is UIWebView (WebKit based)
Android is Android WebView

Mac & iOS WebKit can handle it (we had originally planned to use Chromium
on everything to get a completely consistent experience but had to
withdraw it due to Mac specific CEF bugs).

On Android there is an extra step:

If your PDF is at:

You need to wrap it with the Google doc viewer by setting the widget URL
on Android to:

Chromium should be able to handle PDF on Windows/Linux. That said I did
just see a crash when trying it just now on Windows (avoidable for now by
