Hi, Currently I'm trying to add same set of Users to 2 Custom Audience of sub-types "OFFLINE_EVENTS" and "CUSTOM". But, I can see that users are not adding to the 'Offline_Events' type; though it is successfully adding to the 'Custom' type using the end-point POST /<audience_id>/users end-point.

Is custom-audience of any type accepts user via POST /<audience_id>/users end-point? Please share your thoughts.

Thanks.
