As your organization refreshes sandbox or developer environments with Salesforce, this will impact any connected GRAX applications. However, preventing related issues, and getting GRAX up and running again on the new environment, is fairly easy.
Before the refresh, ensure that the Admin Email Address is set to a valid email address. When the old sandbox becomes unavailable, the GRAX app will send a self-service email to that address with a link allowing you to connect the app to a new org. Follow that link and login with the new sandbox's credentials.
