I've experienced this too; sure,
work is getting done, but it's so difficult to be creative in a way that gets people excited and thinking about problems and their solutions to make our (and our user's) lives better.
Coming up with projects that are impactful and novel is a large part of our jobs, and creative velocity has nose-dived since everyone went remote. There's just (to me) no substitute for hallway chat, overhearing people arguing and getting involved, or coming across an interesting white boarding conversation. One person at a time talking on a scheduled webex is just not at all the same.
