More tips in the category of 'forget about the usability, just go with it', but now Amazon Prime Video:
To play a video on your tv, first open the app on your tv, then select your profile, find your series, select the season, find the episode, click ok to play it. Then repeat all previous steps because the app crashed. Always the first time you use it, without fail. Open the app again, select profile, series, season, episode, click ok. This second time it never crashes. Now click ok again to skip the advert. Yes advert, despite paying for a subscription, but you can skip it. Now your episode plays. Happy watching!
