It's changing super fast. I am using it on the desktop mostly and when I tried on my phone there were issues yes. But do try it out again in a few weeks.
(I am actually using zellij on the remote and using various CLIs more than I am using only opencode on the web. I was using wezterm mux until about a week ago but the current state of the terminal is not very good for this scenario. It seems like almost all the CLIs are choking because of nodejs ink library)
