It is not recommended to change reporting source from Target to Analytics (A4T) after the activity has been started. If you need to look at the data in Analytics what is recommended is to end the existing activity and re-create it and this time set Analytics (A4T) as the reporting source.
If this satisfies your query please like, mark as helpful and mark as answer. Otherwise lets keep the conversation going. Hope you have a wonderful day.
OK thanks so what it sounds like, its not possible to in anyway see this test data in analytics to be able to query it against other onsite conversions once the test was pushed live in its current state
we're also not able to add any additional new metrics into the current live test without having to stop it and restart it.
