@trojan_horse If you can identify whether the customer is looking to report a technical issue/direct complaint very well you can use dynamic content for this purpose.

@YashPa2 You have a content experiment in AJO that you can use for the A/B test. Documentation: https://experienceleague.adobe.com/en/docs/journey-optimizer/using/content-management/content-experiment/content-experiment

@jm_11 It's not stored in any dataset in AJO. Instead, you should get the responses/response code for such API requests for those who are getting dropped and track them.

@Toni_Hernandez You should be able to use the collection data as a product listing feature in transactional messages or use the visibility condition to show/hide the structure.  https://experienceleague.adobe.com/en/docs/campaign-standard/using/designing-content/using-product-listings

@CCG23 Sharing the example query condition that matches with the count on the subscription service.    If there's any data count mismatch open a ticket with adobe support to figure out what's going on.  

Set the resource as a tracking log and add delivery details in the query to pull the 1day campaign tracking report.  

@TejasviMu1 You can schedule a query to obtain the information needed about the number of unsuccessful emails sent compared to successful emails sent in the journey, and store the results in a dataset. But you can't use journey/campaign to send notification that includes the dataset information. Ins...

@MANDM123 You won't be able to do that using a query. If you're looking to get all the workflows, deliveries, etc, that are currently running you can do that using query activity. But if you want to know more about backend processes that are running you may open a ticket with adobe support.

@SarojMo There's no change dimension in ACS. But the tracking log has its Date field (logDate) which can be helpful. If not could you provide more context on what you're trying to achieve?

You can't do anything on this. Not sure whether adobe can turn off this warning due to the way product licensing is tied to HIPAA. But you can reach out to Adobe support and ask about this.
