It looks like SOTAMAPS is currently not able to load the summit list once you choose an Association/Region.
I tried a couple of different Associations, and picking Regions with only a few summits just in case it was a latency issue. No Dice. @N0MAP was also having issues too.
yah it seems to be hit or miss. Rex/KE6Mt was fine, but I received a txt from K6CPR also having issues. so something is off. I am using chrome in both cases I tried, not sure of the others
