Gentle reminder: cashu.me supports nostr wallet connect (NWC).

Settings -> Link Wallet -> Enable Nostr Wallet Connect -> copy that thang and paste it in your nostr client 

You need to keep the wallet open in the background to zap. I've been zapping like this from my nut stash for the last few months.
