I have 3 DataSources,

DS1 (Web Pixel) DS2 (Web Pixel) DS3 (APP SDK)

I shared the data from APP SDK DS3 to the DS2, and has confirmed that SDK send event to dataSource properly.

Now, what I want to do is create custom conversion for the second dataSource, But the I can only see web event instead of APP Event.

Creating custom audience using APP Event is totally fine. was wondering what went wrong
