Hello!
Here's an issue I came across originally in 1.1, but looks to affect 2.2 as well:
1.) Create a dynamic audience and set audience rules
2.) Copy the audience
3.) Delete the audience created in step 1
4.) Check the rules for the copy of the audience
Result: The rules are missing
Expected: The rules copied from the original audience are still in tact.
Again, I ended up making a fix for this because the issue was urgent, which I've attached. It apparently had to do with the collection not being updated to the new cohortid on creation.
Thanks,
Michael
