After pressing the "Purge" button, the queue is purged as expected, bu tthe user is taken back to the same page with the "Purge" button.
This is misleading as a user might not realize that the Queue is already purged (there is no feedback) and press the button repeatedly.
Ideally, after purging, the app should take the user back to the home page.

In the code, it navigates back to the previous page, but this being the submit for the purge button, the previous page ends up being the same page.
