Please describe your bug.

I have a long-ish running PreSignUp lambda function. When the user clicks "sign up" there is no indication that they successfully clicked the button.

Screen recording: https://github.com/aws-amplify/amplify-ui/assets/4824042/0b4e71a2-1874-4cce-b1f7-e22e29005cdd

After the pre signup lambda completes, THEN the spinner starts spinning.

What's the expected behaviour?

Ideally, the spinner would start spinning right away before the pre signup lambda is invoked

Help us reproduce the bug!

Clone the repo, install dependencies, and deploy resources:

git clone --single-branch --branch no-spinner https://github.com/johnpc/autoconfirm-signup-authenticator-bug no-spinner
cd no-spinner
npm install
npx amplify sandbox

Then run

npm run dev

Visit http://localhost:3000 and attempt to sign up. You'll notice that the spinner doesn't spin right away

Is there any update on this or a workaround? I'm running into the same issue after upgrading from amplify v5 and I have not been able to find any solutions

We have a pre signup lambda trigger set in cognito that auto-confirms the user. The code for it was copied verbatim from the AWS cognito docs here

https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-pre-sign-up.html#aws-lambda-triggers-pre-registration-example-2

I'm also running into an issue with the signup where any error message will only be displayed once. For example, a user that already exists attempts to signup, and is shown the error message returned by Cognito with the UsernameExistsException. But, if you clear that error message and then hit signup again, you are not shown any error message. I'm assuming this issue may be related since it's only happening on signup and not signin?

This, along with the no spinner showing up, is a pretty big blocker for us at the moment so any help would be much appreciated!
