Easily Share Remarketing Lists With Your Manager Account
https://support.google.comLast year, Google announced that you can enable continuous audience sharing in your manager accounts. Starting today, you can now enable continuous audience sharing from your sub-accounts as well.
When you opt in to continuous audience sharing, any existing and future remarketing lists you create from sub-accounts will be automatically shared with your manager account. This update means that you don’t have to create new audience lists or manually select audiences from each account.
