I am always confused when someone calls a "stand-up meeting" where everyone is sitting down in their own home. Usually starting with personal updates from everyone and catching up.

The whole point of a "stand-up meeting" is to keep it as short as possible (because standing up is uncomfortable). If you remove that it inevitably stretches into those hour-long meetings where no one can stay focused while everybody else gives super long updates and people find something else to do (not hard in your own environment) while waiting their turn.

The fix is to have a clear agenda and someone actively running the meeting to keep it on track, keep it moving, and push conversations that don't interest the larger group to subsequent smaller meetings or email.

You have to adjust for the lack of discomfort and social clues.
