I'm in the same situation and I agree that when we are together we do collaborate and plan better. On Zoom, people tend to set their mic on mute and very passively engage. However, once we have to actually execute, being in the office is a negative. In the office, it is impossible for me to put my head down and work for a couple hours without someone showing up at my desk with a question. On Slack, I can set dnd with a status message and flow.
