Crawford didn't immediately become the top PFP user ranking. The change took at least three weeks. I recently noticed that Crawford was first in my ranking even though I have Usyk ahead of him. A friend also found Crawford at the top of his default ranking. Are you seeing it too?
Because the personal P4P list is the same as the public one until you submit your vote on the order of their top 50 fighters.
Sometimes it just auto-resets when a new round of voting rolls around. It’s really not that big a deal though in all honesty.
