The share app picture in IG doesnt work

The app is ok but not too great. I wanted to earn coins to share the app picture but every time I attempt to share, I get a error saying Instagram isnt installed. I know I have Instagram installed because Im getting followers and Im getting likes. So, until I can share this app picture on Instagram to get more coins than the rating will be just average. Im not paying for coins until I see all the features working properly.
