Anywhere in Infuse, when you click on a show, if there is more than one season there’s an episode dropdown.
But if you click or tap on an episode in the “watching” strip at the top, you can only choose that one season.
I feel like this must be a bug, because you can play any episode in that season - so it’s not about only playing the episode being watched.
Is this deliberate behaviour? It’s actually quite annoying, cos if you’re nearing the end of a season, you have to come out of the season display, go into the TV section, select the show and select the season; it doesn’t go straight to the next season as it does if you select it from the list of TV shows
The first attached pic shows an episode of Family Guy selected from “watching”; note there’s no dropdown arrow next to “season 9”. The second pic shows me selecting “Family Guy” from the list of TV shows. Note the dropdown arrow next to the season number
