Two-Factor Auth Setup will not accept numerical codes from newly created Authy 'Firefox Account'

I got a new phone and went to reset my 2FA, scan a new QR, and go about my day.

I successfully removed the old 2FA setup from Authy on my older phone, and from my Mozilla account. I can access my user account settings for my Mozilla account and select to add a new 2FA method.

I land on the page which displays a QR code, which I can scan with Authy, and which immediately shows my account information as confirmation.

However, once I try to enter the first numerical code displayed -- Mozilla's text field declines on "incorrect code". I have done this over several times, tried on both phones, and waited for further numerical codes to be generated from the app. No success.

Right now I am on default email based 2FA and cannot for the life of me get the QR or manual onboarding process to accept a code from my app. I have to return my old phone soon so I was hoping to get some advice and figure this out just in case the issue was due to something there.

Make sure that you have the correct (same) time on all devices because the 6 digit TOTP code is only valid for 30 seconds. You can try to scan the QR code with your barcode scanner and pass the otpauth:// URL to Authy.

You can also try to install other authenticator apps like Google Authenticator temporarily and compare the generated codes to see whether they work.
