Been on Nostr for a long time now.
Still can't make zaps work decently.
I zap notes, nothing happens.
I connect alby: fails
I connect with coinos + NWC (thanks for giving the actual string that you need to copy paste, you're the only ones doing that in a readable way).
- still fails though.
Receiving comes in on a totally different old wallet for some reason, don't know where or what. But that works.

What does NWC exactly do? As it connects a lightning wallet to a nostr account? But how does the actual transfer done? Never works for me.

I wonder how many people have the same issues, like being on Nostr but having zero benefits from zapping or getting zapped even.
