Unable to change email on account

Summary

I am trying to change the email on my account to another for a little bit better security on my part. While doing this process I noticed: 1) when I change the email the authenticator app verification fails to accept my 6 digit code. I'm assuming because it is tied to the email. 2) when I changed the email back to the what it originally was the authenticator works but I'm no longer able to change it again. image

Steps to reproduce

1. Change email in account settings
2. Change email back
3. Disable authenticator app
4. Try and change email again.
