I was trying to mirror my Galxey Tab S8 to my Rouku tv, but it wasn't working. Then I turned my wifi off and it started to work. How do I get my rouku tv it to stop buffering with the audio or all together. When I first connected my Galxey Tab S8 with my TV it was doing the same thing. Saw some recommendations changing the resolution, to change the resolution I have to go to screen resolution on my Samsung device but lord and behold I don't have that option I looked everywhere didn't see it. So I guess certain Samsung devices don't have that option. How do I get it to stop buffering.
