When I go to gmail to check my email. Sometimes it does not show the email. It shows a blank white screen on the part where the email is supposed to be. I think what it means when it does that is that it is not loading? And it does that a lot. How do I fix it? It does it in the car, at school, in my house. And sometimes it does it at those places and sometimes it works just fine. How do I stop it from showing the blank screen?
