Just used wos, by going via wallet scan on qr. I attached image. Worked fine loading from photo in wos https://i.nostr.build/4vPoqew2nfBHshnM.jpg
That’s weird. Maybe bug with their scanner. I tested Strike and Zeus using the QR scanner and both work.
Could have also just been a temp issue with @jb55's node which is what should’ve sent the invoice to WoS
I tried another custodian wallet no issue. I agree with your scanner in wos theory
