Echoing this. Navigation is better and clearer on desktop. The mobile apps works really well once you know what you're doing. Part of onboarding into Zulip is being able to get an "overview" of the community and the discussions that are currently happening, and this is easier on desktop.

As a developer I don't like it, but reality doesn't have to appease me.
