Worked fine for me in Edge on my s23 Ultra.

It works but I can't cast to my TV via Google Chromecast. Is this feature not available with a T-Mobile subscription?

Having issues with this since they offered the Tuesdays promo…. I activated it on time, it worked for my first couple tries watching the good ole Texas Rangers games then it stopped working, I have tried to restore my account try different log ins I have contact MLB and T-Mobile… MLB was no help, T Mobile said they were going to elevate my problem and get back to me…. that was over two weeks ago… needless to say I am not happy with T-Mobile right now for dropping the ball.
