Cannot load structures from command blocks when using realms pro

In the new Bedrock Pro realms subscription, structure files cannot be accessed by command blocks. I recently subscribed to the pro subscription and uploaded an existing world I had. I was then unable to load any new or existing structures from command blocks. This bug also appears to affect the /structure command in text chat.

Steps to reproduce:

1: Create a new world in a pro subscription realm

2: Save a structure using a structure block

3: Attempt to load that structure using the /structure command

Expected result: Structure loads in

Actual result: Error message
