Great app, but.....

It works great at school, everything is fast BUT. For some reason if I log out of my Snapchat at school it wont let me log back in! So I had to download another VPN to log back in. & also the VPN turns off within 20-30 mins of it being on so thats not fun.
Overall this app gets a 4 star. Its totally recommended by me!???
