I have the exact same problem.
In this one I choose the top “Custom Overkiz PR#71644”
I then get this pop-up:
If I press the “configure one more instance of Custom Overkiz PR#71644” nothing happens at all. There is no update in the log either. The pop-up still remains up. If I press configure on one of the discovered devices I get the following pop-up where there is no choice to make regarding Hub (so can’t choose Tahoma Developer Mode)
