Why is my Yahoo Email taking so long to open.?

There is no link to go back that is what yahoo has failed to let users know.But there are two ways to go back that I know of see below to see what I did and it did work. There are large numbers of users on here with similar issues.Two ways to back to the other mail that I know of.The new beta mail they say it's 2X faster it's really 10X slower I had it I lost more than half my mail folders.I did a live chat session w/Yahoo told them if I can't go back I will leave yahoo they switched back.Two ways to switch back you can go & do a like chat session with a Yahoo customer service rep/agent like I did.To do this go here.Click on the link below to do your live chat. http://help.yahoo.com/l/us/yahoo/mail/cl%E2%80%A6 Direct link to chat w/yahoo https://sales.liveperson.net/hc/63758332%E2%80%A6 And the other way is if you reduce your screen down just not sure how far down.But if you reduce it down far enough you will see an option to switch back.This will not switch you back to the all new mail it will switch you back to the Yahoo classic mail.Or you can just try emailing Yahoo with your issues that will take some time 3-4 days if your lucky.
