No doubt, Snapchat is an awesome and a good app, but sometimes it starts showing an irritating option of Sending and gets stuck on it. It happens because of some internal issues like overloaded cache and outdated version that slows down the app performance. To solve it, restart your phone. Clear cache from Snapchat settings and check the performance of Snapchat. If the issue does not solve after it, reinstall the app to fix the error.
