I agree there was a good head of steam where people were able to quietly and independently work through their "list" of stuff they wanted to do for ages but never had the chance to etc, or whatever had previously been planned out.
Now months later I feel like things are starting to grind a bit and productivity is starting to wane because the "pipe" is starting to dry up. Those ad hoc conversations that lead to a new feature, bumping into someone in the corridor who mentions some big issue they're having, meeting and talking to end users, the offsites to work out the strategy for next quarter, day-long workshops with UX and management and users and post-it notes galore where we thrash out ideas and concepts are a distant memory. Instead we have stilted video calls where people sit on mute 95% of the time and there simply is not as much collaboration as there was before.
Sure stuff still happens, but it feels like to me that the "spark" from people who usually generate ideas and set the agenda/work items is reduced significantly - if not entirely gone - and people are just going through the motions somewhat mechanically and "doing the best they can given the circumstances" etc.
