I can recomend https://github.com/firsttris/plugin.video.sendtokodi for youtube .. you can share the videos from your phone but you have to deactivate the youtube-addon .. the advantage is you can share videos from a lot of other sites to .. there is a list of site that work with this addon on github
as backup you can try youtube for trailers from the slyguy-repo .. this addon works without api

On kodi there is an daddylive addon that works for me .. if your isp blocks it, you could change your dns server ..
