I'm using a Tab S9 Ultra and although I could connect to my tv (Sony), the initial connection was very laggy and unstable resulting in blocky frozen Images on tv screen with constant notifications on the tablet that the connection was unstable and to try again. Eventually the connection was severed and the link lost. However, when I did try again and reconnect the connection was perfect with no issues. It remains so.
What I will say though is if it's anything like DeX then the connection needs to be started when the TV is changed to the screen mirroring input source. DeX will not connect if the TV is on any other input source ie HDMI 1, Digital etc...only screen mirroring. So if your TV has the screen mirroring input source then switch to that first and then try mirroring again.
