Users not added to Dynamic group

I have created a dynamic rule for users that have a license assigned to them for Microsoft Project Professional.

I have a user that is assigned this license:

According to this article

https://docs.microsoft.com/en-us/azure/active-directory/users-groups-roles/groups-dynamic-membership#multi-value-properties

I should be able to create a dynamic group and have users with this license assigned/enabled, and have them dynamically added to the group, (or inherited), using hte "assignedPlans" property.

I found the Project Online Professional Service ID here: https://docs.microsoft.com/en-us/azure/active-directory/users-groups-roles/licensing-service-plan-reference

Then created the following Dynamic Memebership rule:

The rule created successfully and evaluated, processed, and shows as "update complete".  However, my user has not been added to the group, nor does his user object show him as having inherited the group as a result of this dynamic group rule.

Please help!
