Super slow ads-b loading of nexrad - with missing blocks and low resolution

This is a neat program but I am having
one issue that I cant seem to get resolved. The nexrad weather and text weather load instantly when connected to wifi, but with ADS-B they load so slowly that it is basically unusable. Imnot sure whether or not the problem is the app or some connectability setting. Ive written two emails and a week later I have yet to hear back. Until I can figure out what the problem is, this app is unuseable for me. With this sorted out, it would be a great app!
