Qualified play through rate (recommendations) has dropped to 0% over the past few days

My game’s “Qualified play through rate (recommendations)” has dropped to a straight 0.00% over the past 2 days, even though for the past 56 days it has been consistently high. I assume such a random, sudden drop one day to the next can’t be natural? Below is my game’s playthrough rate for the past 56 days. The active thumbnails for home recommendations haven’t been changed.
