I know Many Many people have been rightfully describing their issues and concerns with the latest Twitch Update and the more people that can accurately explain how the new UI is interfering with users ability to enjoy this platform. I would like to bring attention to how statements made in the Update Announcement Blog post are not representative of my personal experience, and would encourage other users to do the same.
First I would like to say that the new UI is not intuitive for a first time user, I am still fairly new to Twitch as a platform, but the new Home page is incredibly daunting and even with the stream muted, immediately having an (often random) stream playing is distracting and makes it harder to process the rest of the apps pages. Previously I was able to open the app and immediately locate my followed Live accounts, after the update it took me several minutes even with the following button labeled to locate it because of how the white overlay appears. Even with the feed autoplay turned off (which I had to search through the settings to even find since its location was not specified by the blog and that option not described anywhere else) the amount of information in a transparent overlay on top of an unrelated image is distracting and makes processing what is happening in the app difficult, Especially since mobile should be optimized for a smaller screen.

Second, having streams and clips being on the same page as the Following button means that I am often misclicking and/or accidentally swiping disrupting my ability to effectively use the mobile advantage of being able to quickly check information from my phone. A large advantage of having a mobile app I feel, besides being able to use the platform on the go, should be to engage with the platform in quick passing ways, in the blog they mention that the goal of this new home page is to do that, but instead I find myself clicking away from the stream I wanted to watch by accident when trying to join, as well as choosing to check who is live and stream schedule exclusively on desktop because the new UI makes finding that information harder instead of easier.
Third, Swiping between streams is tiring, so many other apps require quick swiping, and part of the appeal of becoming a twitch user for me was having a place to watch and engage with Long Form content without that requirement. I can go to Snapchat, and TikTok and Instagram, and Linkden if I want to repeatedly swipe. Now with both Youtube and and Twitch pushing short form clips content it really makes me want to stop using these platforms all together.
TL:DR The new UI is not intuitive to new users, the Home Page buttons being on a transparent overlay with live streams playing (unless manually paused) makes it especially difficult to use, the combination of the Discovery Feed with the Clips feed with the Following Button makes it difficult to quickly navigate to the desired category without inadvertently swiping to the wrong feed, and the changes to the Discovery Feed to emulate short form content social media apps dis-incentivizes me to use the App at best and actively pushes me to seek other forms of media.
