Hi
Just to make sure that we are on the same page, I recommend going through our How to create a customer journey map blog article.
Could you please provide a detailed description of the issue and steps that have led to it?
Additionally, can you please send a temporary Support PIN for this document? This will allow me to take a closer look at the issue you’re experiencing. For more information on generating a Support PIN, check out this Help Center article.
I appreciate your help and patience!
