We’ve started rolling out a new health check on experiments (gates coming soon) to help teams more easily catch any SDK configuration issues that may be impacting experiment assignment.
The new “Group Assignment Health” check surfaces if there are a high percentage of checks with assignment reasons like "Uninitialized" or "InvalidBootstrap" which might indicate experiment assignment is not configured correctly. You can view an hourly breakdown of assignment reason via the View Assignment Reasons CTA.
To read more about what each assignment reason means and how to debug, see our docs here.
