I was never able to get NWC to work in the web app on nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg .. the solution is to use a browser extension like Alby.. if you do that, you can put your NWC string into Alby and it will work to zap on Primal, I've tested here. Here is a tutorial: https://rizful.com/get_on_nostr_today

My NWC string doesn’t work with Alby extension either. I run my own NWC service that’s connected to my my cash wallet on Strike.
And, did you try this with your NWC string? https://supertestnet.github.io/nwc_tester/
No, but it works with Damus
Primal is not broadcasting the NWC request event when I zap for some reason
Also try nostr:npub1yzvxlwp7wawed5vgefwfmugvumtp8c8t0etk3g8sky4n0ndvyxesnxrf8q with alby browser extension.. our guide is here: https://rizful.com/get_on_nostr_today
