Whatsapp not auto downloading media

As the title says, I have to physically press the download arrow to retrieve any sort of media..ive cleared the cache, factory reset my phone and the problem still persists..sometimes a message won't even pop up until I open the app. All was fine until a couple of months ago now it's just unreliable. Any help would be appreciated
