Problems with "improved" webmail

1. It is slow to load. 2. 50% of the time it doesn't load at all. Error message of "illegal method" (or something like that). 3. Won't load at all unless I click on "In Private" browsing. (found this out by accident) 4. Now, (new problem today) I can't Reply to emails. 5. Platform does not display the account or username that I am logged in as. I have multiple e-mail addresses and it gets confusing when I forget which one I;m on. Old webmail had "logout Joe" or "logout Bob" display. Overall, the new service is terrible. Can you bring back the old one please? I see ZERO improvement.
