Hello everyone,
Indeed, the distribution of favorites is impacted by the latest Vinted bug: the mixed display of items… A Vintie reports it here: Nouveau bug vinted articles mélangés
As a result, favorites are no longer distributed to your most recent items but to the items that Vinted wants to display to others 
As I say in the post I linked, the fact that the « Sort by newest » button still exists makes me think that this is a potential temporary bug. Let’s wait and see how they stabilize the display to know how Clemz will adapt!
