Same for me on the tracker - Eligibility got updated to "Completed" today.The PR tracker just updated today, looks like it updates every 7 days? (Since it was last updated on Feb 1). They just officially posted the news about the new tracker so we’ll see how it goes.
Anyway, Eligibility for me switch from Not Started to Completed today but my spouse remains Not Started.
Background Check is Not Started, which matches with what says in my application.
