Just tried zapping from Primal and got this. https://m.primal.net/IKJQ.jpg
Same.
Try now
Got a “cannot complete the payment. user not found on destination server.” this time.
Shit. Maybe this breaks lightning addresses
Might just be a Primal thing. Just sent 21 sats successfully via Alby.
I am able to successfully zap this user using the primal wallet. It looks like changing his lightning address worked. Let me know if it works for you
