You don't have access to this learning item - Government Cage

We are part of the oracle government cage in the UK

We have an example of a learner accessing learning assignments outside of the UK.

They can access the learning tile and can view their assignments in My Learning Experiences, however, when clicking into the assignment, they are presented with the message ' You don't have access to this learning item'.

This is not an issue for learners who access the learning while in the UK.

I can't find anything in the documentation (internally or oracle docs) that specifically states that they're receiving this message because they're based outside of the UK. Please could anyone advise where this is configured or if this is usual behaviour.
