Yeah, this thing sucks.
It is actually ok in general, but the UI is horrible and the hard-coding of useless Health Tips at the top of the home page, which takes up half the screen, is some kind of particularly insidious developer affliction. Cue special circle of Hell...
To get rid of this you have to roll back to Samsung Health 6.25.1.011 (arm64-v8a + arm-v7a) (Android 8.0+).
Then, or rather before, disable auto-updates of apps from both Galaxy Store and Play Store, as they will both try and auto-update this app. Unbelievable.
Samsung, you really make it hard to like you, though you are not the least likeable of personal health apps, that position is held by Xiaomi.
