yeah, except when i click ‘sign-in’ - nothing happens.
correction: it simply reloads the page.
edit 2: it seems Firefox’s default tracking protection breaks cloudflares support sign-in. Disabling it allows me to log-in to it.
but anyhow, I should be able to reply via email - it’s kinda unacceptable for a service provider to reject emails from customers by way of spam filter.
