"Data 360 in Flows" module is bugged

Hello, 

This module seems bugged:

https://trailhead.salesforce.com/fr/content/learn/modules/data-cloud-in-flows/set-up-a-custom-data-cloud-playground?journey=data-360&trail_id=data-cloud-explore-setup-to-activation

Step 1: Create Data Streams from a Data Kit

-> this one works fine 

Step 2: Create a Calculated Insight

-> this one doesnt work 

If i create from kit just like trailhead request to do it i have this: 

 i verified the following: 

- Data 360 sync user does have access to the custom salesforce objects 

- i have all existing permission set possible assigned to me 

- the dmos do exist  with ready status

so I tried 2 things: 

- Recreate multiple playground, no success, always same error 

- Create by myself the calculated insight through the builder (following what the sql is doing) 

for latest option i have still an issue running the insight 

any idea guys? thank you
