Thank you! I too was losing my mind trying to find the app, and then looked for the widget on the watch, tapped, and then was prompted to download! Could not find it anywhere else.
I followed this link and downloaded the app on my Note 20 Ultra. When I open the app it says no compatiable watch found. I have a Galaxy Watch 3. All software is up to date and I have powered off each device multiple times. Any idea?
@userDeZISnSiln did you happen to catch what @Adaboy said? His Watch3 was only recognized after going through the tutorial. Maybe look into that...? Honestly my Active2 wasn't recognized right away either after installing the app. I believe I watched a tutorial first too. Samsung probably wants us to view the tutorial before it connects to the watch to cover their rear end legally. I hope the best! Mine is working fine now.
If you haven't figured it out yet, I would say reboot your active 2. Shut it off first, then after it has shut off, keep the bottom button pressed in until you see the word "rebooting" on the watch face. After it has started up. See if it recognizes the watch. You might want to restart your phone too... Hope that helps!
