If you're not able to access your induction, it's possible you have declined your invitation by mistake and need it renewed. If that's the case, you can change it back to its original state through the three dots on its top right corner.
In order to achieve this, you need to access your invitations screen. That's the landing page after you register or log in.
If you're on the settings view, you can press the down arrow at the bar at the top and choose My Invitations.
Hit the three dots opposite to the Declined word on the invitation you would like to renew and choose Undo.
Hit Renew on the pop-up to confirm your choice. This will revert the invitation back to a pending state where you can accept it and start your induction.
