Keep receiving "Invalid two-step authentication code" when trying to set up 2-step authentication for Mozilla

Hi all, I'm in the process of increasing security across my accounts and have been unable to set up 2-step authentication for my Mozilla account. I've been scanning the QR code and inserting the prompted code, but to no avail. I tried using both Authy and Google Authenticator and am not sure what's causing the issue. Has anyone else had this problem? I've had no issues setting up two factor authentication across my other accounts, but Mozilla is proving troublesome for whatever reason. Let me know if you have any tips. I appreciate any help!
