Hi to all devs and also users of Mautic legendary software. I’d like to discuss the results of A/B test I received from my Mautic.

Simply by running A/B test together with a segment email, I can see the “winner” badge on one of the variants. But when I open the exact winner (the variant of a parent), there are missing all statistic data in the graph (axis X: Email sent; Email read; Email failed; Clicked; Unsubscribed; Bounced). All useful information I’d like to know about variants are empty.

Is it only me who has this kind of issue all is there another reason I do not understand how to evaluate A/B tests in Mautic?
