I have now fully uninstalled Instagram until things get fixed because I'm getting annoyed at this, It won't let me post things, I can't send messages to people, it constantly says "posting" even after 7 hours after I had originally planned to post or send whatever I was sending. And seeing from most recent reviews I'm not the only person having problems with this. Fix your app please. I have shut my phone off, restarted my phone, uninstalled and reinstalled the app, even went and cleared data.
