I have a Galaxy Watch Active 2 and version 2.0.0 for Galaxy Watch Designer.
I just can’t seem to connect my watch (I used the 40mm and 44mm). Followed all instructions and used sdboverbt as an alternative and tried using my phone as a hotspot to no avail.
I use a macbook by the way. Not sure if this is an issue nowadays. I can’t use windows since mine is very old.
