Difficulty Navigating Amazon TV App

[CivilTwilight]

Need help with my purchases. After hoping for a UI overhaul for years, the Amazon tv app is worse than ever before. There are titles I purchased that are no longer listed in the store that I can access on my PC but not on the smart tv app. My purchases show up as an endless scroll that I can't filter. My Watchlist and My Purchases have been relegated to one section with only a handful of titles showing up at once with no ability to filter by alphabet. The recently viewed tab is also gone. Any ideas of possible workarounds or is the Amazon tv app even more worthless than before?

Edit: Found a workaround for anyone curious. Search for delisted titles from your digital orders, click the link, and then add to your watchlist. It's crazy that this is the easiest way to access stuff from your own library, but at least it still works.
