Presing the 'Sign in' button gives and error "Blocked by Content Security Policy - This page has a content security policy that prevents it from being loaded in this way.
Firefox prevented this page from loading in this way because the page has a content security policy that disallows it."
I was signed in to an account on old and invalid email address, I exited the account, with the Idea I'd be able to sign into the account my laptop and phone are linked on. The afforementioned message appeared.
Is it possible to circumvent the relevant security policy, and if so how?
