I find the progress is much faster at the office because me and my coworkers can more easily consult with each other on both major and minor stuff. On chat wfh they might answer immediately or 4 hrs from now. so, I can’t get in a semi flow because of long interruptions waiting for answers. also chat is slow and annoying.

I know someone is going to chime in a claim those conversations break flow. That might be true for some particular deep problems but I’ve never seen it affect any team I’ve been on and I have 40 years of work experience. Not saying my experience fits everyone else but I’ve seen no real evidence of it being an actual problem.
