As with any social media application, there are times when a malfunction occurs and it just doesn’t work the way you want it to. Instagram is no exception. You may find yourself asking "why can't i follow people on instagram?"
There are a few things that you can do to try to fix this problem. First, try closing the application and wait a few minutes before opening it again. If this doesn’t work you may need to go as far as uninstalling the application completely and downloading it again to whatever device you are using. Also be sure that all of your settings are correct that allow you to follow people.
