Out of curiosity, what doesn't work for you with Code With Me? The only thing I can think of is that the "client" also needs to have Code With Me installed, instead of a possible browser integration like VSCode has.
Command + click doesn’t always work if there’s a lot of latency, many times the „follow other developer“ feature turns off randomly, often the search breaks or doesn’t work at all, the video & audio inside the IDE causes lag and massive amounts of load (so much that many of our devs switched to discord).
For what it’s worth it works mostly great when the developers pairing together are in the same country, but it’s pretty bad when i.e. a developer from Berlin, Germany pairs with one from Columbus, Ohio. So I guess it’s a latency problem.
