Are you having an issue like this? ↓
As you can see in this video the builder is doing something weird when you save, it's showing the pop up where you have to put the code one more time, however, you've already done that, solution: close that new pop up that is showing.
Since your 2-FA is already saved, you don't have to wait for another code.
Also, don't worry, this is getting fixed as you read this article.
Thank you very much for your patience and comprehension.
