I was having issues with getting the location to work on Firefox with my Macbook - I was hitting accept on the location access prompt, double checking the settings afterwards, turning off all my privacy / security extensions etc etc - and was having the Paydala popup just hang and not do anything.
The solution was turning on location services in the system settings, not just my browser settings. For Macs this is System Settings > Privacy & Security > Location Services and then turn it on for your browser. IDK on non-Macs, but probably something similar!
Hope this helps some people if they run into the same issue
