Thank you for the reply! I did not send an invoice, so I think that this means the invoice is from them, meaning they initiated a zap, but then it didn't complete for a variety or reasons -- connectivity issues, or they canceled, or their wallet hit a budget limit or otherwise declined, or etc etc but all of the possibilities are not something I did or did not do. If I have that wrong, please let me know.
Thank you, Oh Zeus. 🌩️
