Cognito existing user pool: Make the email address case insensitive

Hey Dylan,

First, thanks for the really detailed answer.

Regarding the manual changes suggested: It looks like the step you're describing are through the old console. I tried it but since it's an existing pool, the editing is blocked and I can't change this setup.

Regarding the CF template,: You're setting the CaseInsensitive flag at the attribute level, which is different than what I saw here. Should I do both?

Thanks,

Thomas
