We want to share a Smartsheet with others, but we only want them to see certain parts. To do this, we created a filter and set it to be the default view for people with viewer access. However, when we tested this with a team member who had viewer access, they were able to exit the filter. We want to prevent the person who receives the Smartsheet from changing the default filter as we do not want them to see all of the information on the sheet. Is this possible? If so, what would be a solution for this?
