Photos not yet available after create webhook delivered

We are working on our webhook implementation, and are finding that after the create POST, photos are not available when we do a GET to the getActivityById endpoint. Assuming this is a timing issue, it would be great to have them as part of the update fields in an update POST. Right now the getLoggedInAthleteActivities endpoint is more consistent than webhooks and the data provided for both create and update events - we'd love for that to be swapped so we can deliver a better experience for our users.
