Billing statements - why so difficult and slow to obtain?

I have been signed up for electronic delivery for years now but in the past year or so, it has almost become impossible to find and download a copy of the monthly billing statement. Today, despite logging in via MS Edge and then Chrome, I continue to get this error - "Cannot read properties of undefined (reading 'slice')" . I am using a Windows 11 PC, fully updated and additionally, the entire process of getting to your billing area, it is always super slow loading these pages. As I stated in the beginning, this has been going on now for nearly a year. I just spent 30 minutes trying to get a statement. Why don't you include a link in the emails you send notifying customers of their payment due and please, check why the PC access is so slow, not sure if it is because you focus on smartphone access or what but it is way too slow!
