Description
Bug Description
I am trying to filter for cookieless users based on their Distinct ID that contains $posthog_cookieless.
Even though I am seeing the value in multiple events, the filter is producing no events.
How to reproduce
- Go to Activity
- Filter for Pageview and Distinct ID under Event Metadata
For context, we just started to roll out our cookieless setting when this start to happened. We are also seeing a significant drop in traffic counts.

Start in the Activity view and reproduce the Pageview filter combined with Distinct ID matching the reported cookieless value. Trace how the Distinct ID filter is applied to events, then verify that matching events appear and that the result is consistent with the cookieless setting.
