I would suggest having one device stay connected to app.glowforge.com since that has all the setup instructions and you can get photos of what is supposed to be happening.
There are no photos in the support/setup routine of the screens that pop up when you are connected to the Glowforge adhoc setup network unfortunately so you aren’t quite sure what to expect.
Is the button still teal or has it changed color?
In the wifi/mobile device browser window which is connected only to the Glowforge wifi network, then go to setup.glowforge.com on that one. I wish I would have recorded the actual ip address of the setup page for the wifi handshake routine. I think sometimes things get confused because of going back and forth between home network and glowforge.com and the Glowforge’s adhoc network which piggybacks on an internet connected ip. If the handoff doesn’t go well, people get stuck.
Edit: ok, glad you got it. There are pitfalls to using the same device to do the connection and to start the setup routine.
