We work with partners to help us develop products (external development team) and we want them to have access to Aha and the ability to respond to Todos and Comments. Today, if you are a viewer or reviewer, you see the offering you are assigned along with the product lines above. We only want them to be able to view the offering we assign them to, not the product lines above.
Thank you for your idea. The current behavior that you described here provides users with a way to navigate through the hierarchy to get to products they have access to.
Given the historical support of this idea and other priorities we are unlikely to make changes here at this time. However we will continue to monitor feedback on this idea.
