For shows, the episodes on Trakt should always be listed in the order they aired, so the data is correct. Usually, when shows have other orders you can see those in the alternate orders. They are located above the seasons, in the show’s page.
Thanks for the info, so the air date on Trakt is always the default one.
I think the mobile view got me here, upon a closer inspection I was able to find both the Report Title link and the dropdown to choose the order of the episodes. That’s because I use the mobile app 95% of the time. Good news, right?
