Changing email on 1P account -> iOS re-login quirk

Hello,

First off, this is not a huge deal and I'm not locked out or anything, so we're all good there. I'm just wondering if this is a known issue.

My setup is two mac computers with the full desktop program, and 1Password X in Firefox on both. I also have an iPhone X with the 1Password app. I'm running the latest stable versions of the operating systems and the 1Password apps on both computers and my phone. Everything has been fine, but I ran into a weird issue today when I changed the email address on my 1Password account. It's a Families account and I'm the owner, if that makes a difference, but I don't think it does. It is relevant to this issue, though, that I have 2FA setup on my account with a Yubikey, which is NFC compatible, and a TOTP generator (Google Auth) on my cell.

I logged in to the website (my.1password.com) and changed my email address in my profile there, no big deal. Immediately after I changed the password, my desktop 1Password program (which I was already logged in to) prompted me to re-log in. That went fine, and it prompted for my Yubikey, and all was well. I knew my phone would be next (other computer at home will be later) so I unlocked the phone and opened the 1Password app. It immediately prompted me to login again, as expected, but it kept rejecting my master password, which I 100% know I was typing in correctly. It already had my account info (the new email, and the secret key) filled in but I double-checked those as well. Eventually I got frustrated and clicked "skip for now" or however it was worded, and signed completely out of the 1Password app.

I opened the app back up to log into my account, and it still remembered my (new) email and my secret key. I put in my master password, and it accepted it this time and prompted for my 2FA. I could choose between methods, so I selected NFC and scanned my Yubikey. However, while I was scanning my Yubikey (which accepted just fine), an error message popped up behind the Yubikey screen saying it could not log me in and to try again. I don't remember the exact wording, but I believe it was similar to the message I was getting when it kept rejecting my master password before I did the complete sign-out.

I tried this a few more times, and the same thing happened: log in, select saved account, enter master password, scan NFC, and the error was behind the Yubikey screen again. Eventually I chose the TOTP option for my 2FA, and that worked fine and I am now logged in. But does anyone know why this would happen?

Sorry for the wall of text, but I wanted to be detailed in case this is an actual issue that devs need to be made aware of. I don't think I did anything incorrectly, and I doubt it is anything specific to my account. But I just wanted to put this out there.

Thanks for any feedback!
