Instagram won't let me post a photo?

If you have an apple device: use four fingers to drag up from the bottom of the screen from here hold down on an app icon and remove it by using the minus sign, by doing this you have deleted what your phone has remembered where you were after closing the app.
If you have an android device: open the task manager (on a Samsung hold down the home button) click task manager and select remove.
Hope his has helped!!
