Stakeholders cannot access shared sheets


We have having a consistent issue with stakeholders accessing shared sheets. We are adding them to the sheet and sharing it with them, but stakeholders are getting error messages when trying to access the sheet. I think we are missing a setting somewhere because it is happening with internal and external stakeholders. The error is that the individual is getting says "You don't have access to this item" however, we have included them by clicking "Share" and adding them as a collaborator.

What are we missing?
