I was trying to watch Andor on Disney using a Amazon Fire TV Stick 4K Max 2024 model. At my gf's place. S2:E2 would not launch. Also had the same issue with S2:E4. When trying to launch it would go back to the list of episodes. If I tried again it would go back to the main Disney+ launch page. I used my gf's firestick and her Disney+ account to watch E2, but had to sit through ads since she has the basic plan. I ended up using the Disney+ app on the Smart TV itself to watch E4.
I bought the Fire TV cube, got it overnight. I was able to watch the rest of the season until S2:E12. It would do the same thing as with episodes 2 and 4.
I only had one app that didn't work correctly one time. That was the WNBA app and I forget the issue, other than that no other issues with the fire stick.
Tried all the usual fixes other than a factory reset. Clearing cache/data, uninstalling and reinstalling. And of course the Fire TV Cube. The issue likely has to do with that version of Disney+ on Fire TV and the fact that I have the premium plan. But that's a theory. At home I have a PC, and two game consoles to stream from so this is unlikely to be a big issue for me in the future. For the TV at my gf's place where the issue occurred I'm replacing the Fire TV stick with a Apple TV.
Still would like to know if anyone has a similar issue and what they did to resolve it.
