Whenever I try to follow people on instagram, the follow button turns green and says following than turns right back to blue again. I have tried logging in and out of my account, deleting an reinstalling the app, I unfollowed loads of people and are now only following 28, and I restarted my iPhone. Nothing is working. I have waited a couple hours since the last time I did anything on instagram and it still isn't letting me follow people. It also doesn't let me post comments on other people's accounts. Please help me ☺
