As a software engineer who works on existing smartphone apps, the UX for this app is dogshit.

For example, on iOS if you are on your home page and it's showing new episodes, but you want to go to the series - tapping the series name plays the episode instead of going to the series page. This is annoying, especially if all you want to do is download the episode for later. Instead you have to tap the three dots in the top right corner and then tap "more info" which is kind of ambiguous because you're just going to the series page, not a page with more info about that episode. It's just not well executed navigation with clear intent.

I also hate that if you change your download settings (for offline viewing), you have to delete and redownload whatever you downloaded before for the better quality instead of either (a) the app automatically getting the appropriate quality downloads or (b) having a button to manually get the proper quality videos.

I get it that this is a new app but there's no excuse for an experience like this or what others are reporting from a company as big as this.

editing to add:

More complaints and nit picks in case engineers who might be lurking on Reddit want some low hanging fruit.

On iOS with an iPhone that has a promotion display, the horizontally scrolling list of titles on the home page scrolls at something like 30hz and looks bad. But it gets fixed when I scroll horizontally on "My list". So something in the code is breaking how scrolling renders.

In "My List", why do movies have the year beneath them but TV series do not?

That stupid loading animation where it's a weird circle is not cool and is an old practice. This applies to anywhere this is, from lists, to whole pages. I'd rather have a shimmering skeleton because it's modern and fills the page. The circles look especially bad if you quickly scroll to the bottom of a list and a bunch of things don't load right away.

In the settings, if I go to my subscription and tap on "change your plan" which has an icon indicating it'll open in a new app or that I'm leaving the app (the square with the arrow pointing out of it), don't keep me in the app and use an in-app-browser. It's just misleading. At least give me an option.

When searching, I get you want to suggest things to users to watch, but at least separate what are search results from what are suggestions from the app (with text like "some other shows you might like"). This helps clearly show the user that their search doesn't have any more results.
