I submitted a ticket for this on March 11th and it's still not resolved.  The fullscreen button suddenly stopped working.  When hovering over the icon it says "Normal View" and clicking the icon does nothing.  Is anyone else having or had this issue?  I have logged out and back in.  I've cleared my cache. I'm using the most current version of Chrome.

It may seem like a minor inconvenience, but it's extremely annoying.
