When you press that button, you will return to the previous page you visited.
Topic summary
A Shopify store owner using the Dawn theme is experiencing issues implementing a back button on collection pages.
Tech support was unable to resolve the problem, and a previously suggested script has not worked correctly.
The specific issue: When clicking the back arrow/button, users are randomly redirected to the products page instead of returning to the most recently visited page as expected.
A community member requested the store URL to investigate further, which was provided ([https://8dc92b-15.myshopify.com/]).
The discussion remains open with no resolution yet—awaiting troubleshooting based on the shared store link.
