I noticed that if you type in a person’s callsign in “their callsign”, it will lookup on QRZ (if the option is selected) and fill in the information like state, grid, etc…
However, if you copy the information from the POTA spotting list, it doesn’t lookup the callsign so it never fills out the location info.
Not sure if this would be useful for anyone else, but it might be nice for completeness.
