Have you added the journey to your pass?

Can you post screen shot of your trip and of the error message?

I think so. Added screenshots:

Please remove the personal information from the screen shot. 

Have you followed the steps in the instruction video available on the web page in the link?

I don't think that the journey is connected to the pass. 

I can’t find out how to edit or delete my own posts. Please delete this if you can, admin

We've seen this problem a few times now over the past few days.

Please check for app updates. It looks like you have an iPhone, which means you should have app version 24.0.0 (check under More, scroll to the bottom).

Please enable error logging and then contact customer service and give them all details.
