Personalization attributes - which merge policy

[Michael_Soprano]

1. I create read audience journey - merge policy for profile attributes in personalization syntax would be taken from merge policy from that segment

2. Event journey - default merge policy - email default set up in AJO?

If you update the merge policy for an audience, any active journey referencing that audience must be republished to access the new policy (see documentation).
