If you signed up and were asked to look in your inbox for an email confirmation link, but you've lost the email or accidently deleted it, you can resend it from your account settings.
In the app, find your initials in the top right hand side:
Head to Account Settings:
Beside your primary email address, you can click "Resend verification email"
Check your spam, and if it is in that folder make sure you mark us as a trusted sender / add us to your contact list!
