Snapchat says I have no internet connection when I do
Help!!!
OK so a few days ago I log out of my Snapchat and then when I trying to log back in it said that there was no connection to the internet and I needed to connect to the Internet but I had full bars of Internet I've restarted my phone and also I'v restarted the network settings and I just don't know what to do I've emailed Snapchat but nothing they have suggested has helped also my twitters not letting me see the peoples bios or there tweets and yes the date and time is correct .
