Back arrow on Android won't go back to inbox

Often when I use the back triangle on Android to return to the inbox from an email I'm viewing an error comes up with a link that says "try again"which never works. Why does this happen and how is it remedied to make it work right?

Hitting the back arrow should return it to the previous page that I was viewing before, prior to the one that I'm viewing at the time that I hit the return arrow.  This is a very basic function that used to work on yahoo and still works everywhere else with the exception of yahoo mail.
