The mobile app is kind of pointless anyway, imo. It cannot start an agent session on your computer, it can only be "handed off" an existing session from your computer. I don't use Cloud Agents, because for some reason they can't connect to our Linear instance. So I was only interested in using the mobile app as a proxy for my home system.
It is surprising that they went this route instead of the Claude-code route. The cloud agents are significantly more limiting.
