After Samsung Galaxy Watch 42mm with One UI update, I can't install Samsung health update on the watch. Watch just disconnects when update is installing. I have Samsung Galaxy S9 (One UI) & Samsung Galaxy Watch 42mm (One UI).
I think the new Version comes really with latest Firmware. When i check the Version on the clock (tutorial greatanubis) its the newest Version. But the App on the Smartphone showing it wrong and wants to update. The Problem is the Galaxy Wearable App or the Galaxy Plugin and not the Samsung health app.
I have the same issue on my Samsung Galaxy watch 46. It shows me there is a update for Samsung S Health available, but when I try to update the watches disconnects...

I've managed to update my watch by following step by step the instructions. Had to go with Option 2), since I had no "Update" option for Samsung Health otherwise.
Edit: Nope, it didn't work. The version is the same, after the "update"
