I am having casting issues on my S21 Ultra 5g as my phone is not detecting my TV even though both my phone and the TV are connected to the same WiFi network. I have done restart of my phone and my TV as well but no use. I have the latest software on my phone and on my TV as well. I had no issues casting my phone to my TV on my previous phone which was a Galaxy A70. Anyone else having casting issues with their S21 Ultra or is there something I'm doing wrong.
