This is such a minor thing, I feel kind of stupid reporting it ? But anyway, The link in the confirmation email is not actually defined as a link, making it a bit fiddly to activate your account when on mobile. I think certain mail applications (like gmail) automatically convert it into a clickable link, but not all applications do that. (Also, what are you supposed to call a link that is "clickable"? Is it still a URL if it's not clickable? Seriously, I want to know)
