Cypress Tests become flaky after switching from Okta to Auth0

I have a React app, and normally the tests work like clockwork. However, we’re switching authentication providers from Okta to Auth0. Currently, we have a separate branch from our main one where we’ve swapped out all the Okta stuff for Auth0. This includes adding the proper environment variables. I can locally run the tests on the Auth0 branch successfully. The same tests run fine in CircleCI on the main branch with Okta. The problem is in CircleCI they become slow and flaky. In the videos under the artifacts tab, I notice things like the tests hanging on the Auth0 universal login page, and on some successful logins but not all the time, the app just rerendering over and over again. What’s going?

You may find the Auth0 forums a better place to post the issue, but one thing comes to mind.

What security features does Auth0 have in place for accounts that try and authenticate from a wide range of IP addresses, as this will be what is seen by the central Auth0 platform as Workflows and jobs are executed on the CircleCI platform?

After a bit of looking around, I can sum up my question as

Are your tests tripping any of the sub-systems listed here?
