Emails Timing Out

Seriously Comcast, what are you doing with all email changes???????  First of all, the whole format changed....finally got that done pat...Now, my email screen time's out, and signs me out!!!!  So I have to go back and sign in over and over and over!!  I'm lucky if it comes-up at all!!!  That's running slow, if at all!  What's the scoop over there???  Oh, and also, it's logging me out WHILE I'm on the email page, viewing my emails!!
