Many thanks for the feedback really gentle. What I can just got from that person is the brand of TV (Crown) and SO that is Android (even if user agent taken from his visit statistics visit says Lenovo). He made also a picture of the screen https://www.vibee.tv/wp-content/uploads/2020/05/95666460_2872568879505604_8342785285976752128_nTV.png
The same result I can see when I use dev tool on Chrome https://www.vibee.tv/wp-content/uploads/2020/05/screen.jpg

He also told me that opening by the browser the player works. It’s fail via app https://play.google.com/store/apps/details?id=com.ivanovivee.v2beat

Considering that app (that is just a converted website) works on my android devices and not on Crown TV.
