Description

When switching between different auth0 users within the same browser, the user from useAuth0() will return undefined and the isAuthenticated will return false, even after the user has successfully authenticated with the loginWithRedirect function. This occurs when using the cacheLocation is set to memory

Reproduction

1. Setup an auth0 provider with cacheLocation='memory' useRefreshTokens={true} and useRefreshTokensFallback={true}
2. Use a chrome or microsoft edge browser and authenticate a user and switch between several auth0 accounts.
3. You should notice that after proceeding through the loginWithRedirect and being directed to the client application that intermittently, the user will still be undefined and the isAuthenticated will be false.

We are noticing that this has a higher rate of occurrence when the browser blocks third party cookies

Hi @jsaulsberry-cvet

Can you confirm if this issue occurs only when switching between different users? Additionally, could you share how the onRedirectCallback is being handled in your application?

Just a quick note: if cacheLocation is set to memory, the user information will not persist after a page reload. However, I understand that your use case might differ in this scenario.
