I am running v14 and connecting to macOS Mojave also running v14.
I've noticed that on certain situations, TV refuses to connect or gets stuck. For example, new user logs in and get "data & privacy" prompts or post upgrade from where you again have to answer os prompts or make a choice. Other remote software that we use does not have this issue. I know because I had to switch in order to get past these prompts. We also see this on Windows as well.
This is a show stopper for me and our business and we were looking to do a company wide switch to TV :(
Its a shame as we find it much faster on Macs than other solutions.
