I am attempting to log in to the App Store and Apple community forum, but each time I try, I am told the details are not recognised. However, if I attempt to create a new account, I am told the email address is already in use. How can this be? I know I used the email address to update my details some time ago, but attempting to change the password results in the same old result, address not recognised . I have spent quite some time on this, but am getting nowhere. All help appreciated.
