Hi there!
Apologies for the late reply - our team's recently transitioned over to the Microsoft Q&A platform, and we must have missed your question in the process. Are you still experiencing this share issue? If so, could you tell me more about the steps the sharer took to try running the script?
Many thanks and sorry again to only be getting back to you a month later. I look forward to hearing from you!
-Nancy from the Office Scripts team
