When I try to sign in to my account on my laptop I get a message saying prove you are a human and a blank screen. Can’t get on to help pages because you have to sign in in order to do that. I have two accounts for 2 different shops and it is the same on both. Anyone else got this?
I haven't had this issue, but maybe try clearing your browser cache and try again?
Yes, this has worked for me in the past when I was getting a blank screen for Recaptcha.
