I use Facebook Messenger literally every single day to message my friends and family and have always hated how the mobile app discriminately downloads media content regardless of whether I open the message or not.
Sometimes my friends would attach really long videos or high-resolution shots to their messages, prompting me to completely disable cellular access for Messenger on my iPhone, but then I don't receive their texts on the go.
Wouldn't it be better if Messenger handled data-hungry attachments more intelligently when the user is connected to a cellular network? As per a report by The Next Web a few days ago, a new data saver option is indeed coming to Messenger in a few weeks.
