omfg I got it to work!! I must have copied and pasted this 12+ times already over the last 6 hours. But I was about to post it here, and for some reason it worked when I tried it again. Thank goddd.

Hopefully the rest of the transaction will go smoothly. Thanks for your help!! Haha

Thanks so much for your reply... The issue is my QR code is on my phone--for instance on my digital receipt... or in my screenshots folder, since I took a screenshot. But when the app gets to that page where it turns on the phone camera, as far as I know there's no way to scan a QR code from this setting unless it's on a physical piece of paper?

I've also tried pasting the address at the bottom as you mentioned, but it won't let me. The address is correct, but it won't let me paste anything at all actually.

Your first image looks similar to mine:

However, this is what comes up with I attempt to paste something, or even just click Paste:

Downloaded today from the official site/ Play store.

When I click Send, it turns my phone camera on and there's a message saying : "Scan an Invoice, an Address, an LNURL-pay, a PSBT or a Channel backup."

But there's no option to do anything. There's no option to provide an address or QR code so I can send the funds out. I've been trying for hours now to get this to work somehow. I'm actually trying to buy medicine I really need, so I've been rather stressed about this.

I also found another person reporting the same issue in the Play store last week.

Thanks
