I'm having the same problems with this 'upgraded' email system that everyone is sharing. This one takes the cake....Got the courtesy bill reminder email from Xfinity. Went to click on the 'View and Pay' blue button within THEIR email. DOESN'T open. So then I go to 'My account' and click on the 'View & Pay Now'. At a glacier speed I finally get the dreaded "Hmmmmm, we can't locate this page" text. Too much!!! But woe be to me if I didn't pay on time!
