With the return of NXT UK in the last couple of months, it's disappointing that episodes aren't given their own section on the app or website - they're just under NXT, and it's not always easy to find them.
In addition, episodes are listed by number, unlike Smackdown/Raw/NXT episodes which are listed as date. It makes it that bit more difficult to keep track of which episode I want to watch next, especially as the episodes don't have individual thumbnails on the app, just a generic title image.
Finally, and this is an issue with all WWE programming, is there any way the app on iOS or Xbox could keep track of where I am when watching an episode? If I get interrupted watching an episode or have to come back to it later, I always have to restart from the beginning. On the iOS app there's the option to move to individual sections (of full episodes only, I think?) but those vary drastically in length (one segment on this week's Raw took in 45 minutes including two matches and at least one significant backstage segment) and the menu itself is fiddly to use - you have to tap to bring it up, then scroll through to find the segment you're looking for using segment names that only show up in full when the segment is at the centre of the screen, and which will disappear if you take your finger off screen for more than a second...
It's great to have all the content available, but these minor issues do detract from how easy it is to find and watch the content.
