Bought a Galaxy Watch 7 two years ago, the hardware is good and One UI on the watch itself is also quite good (and the last major update improved it) but Samsung Health is such a shit app. Constant ads for some "courses" or videos and things I don't care about. Downloading my personal data doesn't even work, it sends me right to the browser with an error message that I'm "not logged in correctly" and it wants access to all my pictures & videos (seems like a wrong permission prompt there but when I decline it it also fails with "we need access to all your photos & videos". Why? Just send me a download link via email or use SAF and let me pick a download location).

Thanks to this article I also noticed the UI was redesigned. At least I could keep my layout but it didn't work like it should, it added some useless cards. It also asked about new "optional" data sharing which I of course declined. There is now a notice that my data wasn't backupped to my Samsung account the last 3 days (???) and the data synchronization doesn't work, the buttons do nothing, it just says "disabled" even though everything is enabled... typical Samsung shitware. Haven't noticed anything with AI training (there is no option) but I'm also in the EU.
