Describe the problem you'd like to have solved

Our system has different Auth0 tenants for different environments: QA, Stage, Production
We would like to re-initialize our auth0 client when the user selects a different environment.
We currently do this, but discovered that Auth0 retains some settings from the first environment.

Example:

• start app
• select QA environment
• logout
• select Production environment
• login

This all works until the access token expires. The call to renew the token goes to the QA environment instead of Production.
There must be a singleton or something inside auth0 that does not get cleaned up when we re-initialize the environment.

Describe the ideal solution

Auth0 client should be able to fully dispose and allow the app to create a new instance.
