MatGu On 2.9 the always reloading of restaurants has been turned off if the list of restaurants is already fetched, hence if the customer goes to the item page and clicks on the back button and comes to the restaurant listing page again, the list is not refreshed. (This is Intentional) - this is done to preserve the previous position of the page.
Are you not able to understand that the user can just reload the page and get the updated list of restaurants? (On Chrome and on Safari anywhere the user can pull to refresh or reload the page)
This is not a bug, it's a feature!!!
