Try anything else besides chrome or Chromium based browsers.
There’s likely a wrong mime type set for videos, which any browser that follows the official standard wouldn’t play, google does not follow standards (which is a security issue by itself), and they simply ignore and play it regardless.
This leaves iPhones and iPads users with no option at all to view videos here, as all 3rd party browsers (including Chrome) must use Apple’s web engine.
@revhtree maybe it’s time to fix this bug and relief all of us? It really shouldn’t be that difficult.
