I have the same problem. Did you ever figure it out? I Have had Paypal shopping cart buttons and Paypal checkout on my web site for 19 years. I Logged in to change the shipping calculations for my website and can not find it anywhere. No "Merchant Services" anymore, and the Help instructions do not 'fit' my page format. (No Tools" option anywhere) and there is no "About the business" under "Profile" as indicated in HELP. Also weird is that there is a link to "upgrade to Business account" on my profile page? HUH?.. I have always had a business account in order to be a merchant and have the Shopping Cart. I am still able to create buttons (Add to Cart) but can not locate shipping rate Calculations. When I 'Chatted' I was told my account is a Personal account! however "a Personal account does not have the button creation functionality." Very confusing, and now unable to modify the calculated shipping Like I have been doing since 2000.
