Actual browser show a JW video player but no sub are selectable

[AC Question]

In a previous Android version, through any browser, I was able to watch my preferred website's videos via a version of jwplayer where there was a button to select subtitles and voices and the classical ones. Now via my new android version the embedded player doesn't show any more those buttons.
How can I restore the functionalities on the actual player?
Or how can I change player?

Thx in advance, Mikahel.
