Hello moreland01
You will not see the Swiss Travel Pass Flex in the app until you have activated one of its travel days. Only then will you see the ticket.
To activate a travel date, please go to: activateyourpass.com. You can do this in advance already; the ticket for an activated travel day can be deactivated as often as required. Deactivation must be made before the start of the validity period at 23:59:59 (Swiss local time).
Kind regards,
Roland
