In both the emulator and the TV, video is always pending, when I click play it always stays on * promise pending *.
I tested in 3 different tvs, internet privileges and subdomains added, watching the debug I noticed that the tvs nor try to download the media, it seems that there is something broking the download.
Now by fetch and xmlhttprequest download normally, direct in the tag
Html5 video not work *mp4 and webm*, not download media, not play
