Question 1: since I chose the digital product, I didn't see any button to upload the file. Should I send them manually or can I upload at the page or provide my link in order for them to download the file?
Question 2: I was trying to pay with different browsers and some of them, the invoice, once you paid, it doesn't confirm the transaction, even if my wallet shows that it's been sent correctly. Is this something of myself or is it something wrong with the page?
