Samsung s7 internet and chromecast

[Android Central Question]

My samsung s7 connect to chromecast only on Netflix or YouTube. I can also cast to my tv but I would like to watch a show that doesn't exist on YouTube or Netflix. My husband has a Samsung s9+ and he is able to watch the show. For him the chromecast symbol shows up when he clicks on the show for me it doesn't

Welcome to Android Central! You're trying to cast using the Samsung Internet browser, and the cast icon doesn't show up there? What if you use Chrome instead?
