I did the whole cash.me thing yesterday but I can try again. It’s exhausting. Also interestingly, when I paste the NEC link from nostr:npub1h2qfjpnxau9k7ja9qkf50043xfpfy8j5v60xsqryef64y44puwnq28w8ch into nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 it shows a relay connection. When I go into settings in Damus and click on zaps, the option to select a wallet includes a bunch of named one, not coinos, no NWC link option and a generic LNLink option - which doesn’t work either. 

Begs the question is there any documentation for any of this or is the new “freedom” norm trial and error via people who are willing to help?
