I'm going through the QGIS training, Lesson: Network Analysis, and I've encountered a problem with Network Analyst. When I open the Shortest Path (Pt to Pt) tool, I can set the Vector layer representing network and Path type to calculate, but when I click on the "
..." to set the Start or End Points, nothing happens.
I've searched on this site and Googled around and haven't found anything. I've tried it in both 3.10 and 3.8 and the problem exists in both.
