Perhaps best to call the broadband support team or send an email to customer support?
How to submit your complaint:
Taking a screen shot is pointless, where if you click on your new / recent emails or saved documents under Broadband & Calls > Messages nothing happens, the page doesn't refresh no change in the url (nothing).
It seems the links to the email or documents for me will not open because they don't exist wherever the link is suppose to take you to.
Tried mine and my Dad's account on two different devices and three different internet browsers which was MS Edge, Chrome & Fire Fox.
Also tried my browser in a Private Window with the same unsuccessful result.
My apologies, I just read @MemyselfandI 's comment regarding seeing "page not found" again - I see now that this is only when trying to copy the links. So you are of course right it would be pointless.
Regardless - this has been reported across chat too and I'm told the teams are looking into it - I'll let you know when I have an update.
In my case the document links do not exist although the cursor changes when I hover over them so something should be happening with a click.
Clicking the message links also does nothing but I am able to copy & paste message links to another window. Trouble then is all I get is a "Page not found" page.
Something is definitely broken. I wonder if it could have something to do with the recent retirement of Adobe Flash?
