Issue Summary

If a company had Atlas in the production site and Platform Experiences in the Sandbox, the Sandbox workspace will be set as the default when a user first accesses Atlassian Home after migrating from Atlas to Atlassian Home. This could confuse users, making them think they are viewing their production environment.

Steps to Reproduce

1. Create a sandbox and opt into Platform Experiences for an organization with Atlas in their production site.
2. Wait for the migration from Atlas to Atlassian Home in the production environment.
3. Open Atlassian Home.

Expected Results

The production or the last accessed workspace will open when we access Atlassian Home.

Actual Results

Even if the production site was the last accessed, the Sandbox will be set as the default the first time we access Atlassian Home. 

Workaround

There isn't a workaround for accessing the production site the first time after migration. However, we can switch to the production site using the dropdown menu in the top right corner of the screen. This will direct us to the correct workspace the next time we access Atlassian Home.
