I just zapped myself using my Wallet of Satoshi app & it worked. Might have been a bug in the system last week 😅

I think it was a location thing. You can zap yourself fine only if you're in certain states if zbd is set as your address (at least from my testing)
Thing is my lightning address was initially set to my nostr:npub13ljnkd633c7maxatymv3y2fqq8vt3qk7j3tt0vytv90eztwgha9qmfcfhw address and had been on my nostr:npub1kmwdmhuxvafg05dyap3qmy42jpwztrv9p0uvey3a8803ahlwtmnsnhxqk9 address since I spoke with nostr:npub1fnn2h0tgm2mwnl0kar5ez25wztum2w0q0rrrf326n0ljn999znwsqf4xnx so this shouldn’t be a problem as others have been able to zap ⚡️ us.
Problem might be on your wallet side but thank you for trying.
