My hope was that lockdown would boost recruits and engagement as people has plenty of time at home. But yeah, maybe they have felt other matters to be more important.

Agreed, I was hoping the same. Seems like many are not feeling particularly confident to go out on a limb and try something new (like Hive.) I'm not really sure, but I think there is little more important than getting continuous new users — and providing them with an experience that leads to retention on the platform.
