Multiple third party reports [1] are showing the site has lost ~80% of daily active users and of the < 10 million daily active users left, time spent in the app has decreased from nearly 20 minutes, to less than 3. I'm left to reference third party sites since Meta stopped reporting their numbers officially when it started cratering. That scale of collapse is unlikely to be due to the lack of effective search or a chronological feed.
