Thumbnail Personalization consistently picking worst performing QPTR thumbnail. Is this a bug?

After trying Thumbnail Personalization (TP) for my new game, I have noticed that the algorithm keeps picking the worst QPTR thumbnail to push to users.


Expected behavior

I expect the algorithm to pick the best QTPR thumbnail as the winner & make it get the most impressions. I do not expect the algorithm to consistently push the worst QTPR thumbnail to the most users it can.

I forgot to mention light blue. It seems that light blue performs better than green, yet the algorithm chose to stop pushing it in favor of the worst performing one (green.)

Hi:
Thanks for reporting the issue. We are working on debugging our flow to see what is wrong here. We will update you once we get some findings.
