Following in Facebook Messenger's footsteps, Instagram DM's now show your 'Last Active' time.
UGHHHHH.
Perfect for when you want to know when your bae was last online... but otherwise, kind of stalkerish.
People aren't too keen on this feature at all.
Thankfully, you can actually switch the feature off. It will hide your own activity status, and everyone else's from you. Go to the settings on your profile, scroll to 'Show Activity Status' and turn it off!
Easy!
