I recently came across the issue that I wanted to setup Unifi Talk but I didn't want to buy a talk device just to set it up (this was the recommended way from Unifi)
So I began investigating the code and found out that if you press 10 times on the "Setup Device(s)" text you'll be able to skip the device step.
4.0.2 not working anymore, I'm using the international profile.
It did work for me yesterday, on 4.0.2 installed from scratch and using international profile. Not sure how you are doing it but you have to click 10 times on the text "Setup Device(s)". Not intuitive at all
Click the WORDS "Setup Devices" next to the picture. It's not a setup button, just the H1 text 10 times.
Worked for me on a Cloud Gateway Max in the UK.
UDM Pro here, original method didn't work (Next button grayed out). Followed what @torbell25 said (click the "Setup Devices" text 10 times; or until the Next button became clickable. Everything working and functional with third-party provider (VOIP.MS)
4.0.2 not working anymore, I'm using the international profile.
