I am using Sitecore 10.2 with Dynamic CRM Connector, I run two pipelines
Dynamics Marketing Lists to xDB Reference Sync
Dynamics Marketing Lists to xConnect Sync
Both pipelines are working fine with no errors, but when I go to list the manager and create a segmented list then add the rule where contact is a member of specific list from the Dynamics tenant specific, I can not see all lists which is available in CRM.
Only contact lists can be used as a list source. If you want to use a segmented list as a list source, you must first convert the segmented list to a contact list (this is mentioned in the Sitecore docs).
If a contact list is created but not activated, you can activate it as part of the workflow by changing the Draft state to Deployed (this is mentioned in the Sitecore docs).
Contact list definitions appear in the index only when they are activated using the Marketing Operations API or they are saved with the activated flag set to True (this is mentioned in the Sitecore docs).
