Unable to scan 2FA QR code for Instagram using 1Password in the browser

Thank you for your response. I think the problem was on instagram's side and today, I was able to add the 2FA to 1Password and use it to logon to instagram.

To try to clear it up my initial report if it ever happens again, the error messages were always from Instagram's side. I had previously setup Instagram 2FA with Authy, and I wanted to replace it with 1Password. I deleted my old 2FA entry on Instagram, and when I went to add it from 1Password I got this message, which persisted for more than a week. I wouldn't consistently get this message from Instagram, sometimes Instagram would just fail and say "the code you've entered is not valid". As I said, this problem is resolved now.

Thanks for following up!
