How do I re-set my password?
If you signed up with your email, there is the option 'forgot password' to click on to send a password reset email. Once this has arrived with you, follow the steps.
If you signed up with Facebook, Google or Apple then you need to reset those passwords to reset it on the app.
(Ie if you used your Facebook to log in, then the log in will be the details you used to log in to Facebook)
