If you are having trouble with changing your primary address after doing all the steps, make sure you are updating your PayPal card address as well (if you have one ) that’s the last thing I tried and it worked
Go and click on the profile tab (icon next to log out) > click on the + and ''add'' another/new email address > verify it > go back and click on ''update'' and tick the box underneath that says ''make primary'' > then you should get the remove option by the old now longer primary email. You can remove that one or leave it on as you can have up to 8 email addresses on the one paypal account.
