Figured it out, you need to add nostr: in front of the npub. But they use njump.me and they don't seem to be pulling new notes form the sources I was testing. For example nostr:nprofile1qqsfchg8jvcf9mgsjvl09n6tqpha6alfcahd8cjv4h5cpx87q9mdwlspzdmhxue69uhkuethwvh82arcduhx7mn9qyfhwumn8ghj7cn0w3ejuat50phjummwv5q3yamnwvaz7tmhda6zuat50phjummwv5keahu4
