Transactional Message History visible for Admin but not for Users with "delivery"+"message center" roles
Hi,
According to the access rights configured for our ACCv8 instance, 'delivery' operators should be able to access the 'Transactional message history' folder with read, write, and delete permissions.

However, when trying to access this folder, users in both 'delivery' and 'message center' operator groups are presented with a blank page:

For Admin users, this page is populated with data. What additional permissions are needed for delivery operators?
Thanks,
Skyler
