Hey RandomNym (nprofile…esn4) I am a noob monero user. I went to pay the nymbox invoice with xmr from cake wallet. Scanned the invoice and it was paid. Now I am in a loop paying ever smaller invoices. The fourth one now is for four cents USD. I don't understand why this is the case. What am I missing about monero transactions that would require multiple payments to cover the initial one? Thanks.
