Portfolio not Licensed Error

Hi, I’m starting to see quite a few occurrences of the following in customers issue data:

                  "message":"Portfolio for Jira must be licensed for the Parent Link to be available."

where the custom field is parent link. It seems to have started happening in the last week, any ideas? One of them has said they don’t have portfolio so I’m wondering if it has been a recent change in Jira


I’ve noticed Portfolio is installed on every cloud instance, it’s just unlicensed. The Parent Link custom field is also always present.

I guess this is because it’s a P2 add-on.
