Thanks you for your answer.
I understand what permissions i need to give but i think a "viewer" license can't get this permission. The weird thing is that is some dashboards users can save the view and in other they can't.
Any idea why is that?
Any update on this? Can someone confirm that Viewers should have the customized view option? Does this option depend on site role or only on the project/workbooks permissions?
I believe the custom view options only appears if there are public views available to a user with view only access. They are not allowed to create their own view, but can change to other custom public views. It looks like an explorer licenses is the minimum license allowed to create its own custom view. So if a dashboard has only the default view available a user with 'View' only access would not see the view icon. If there are other public views then the user would see the icon and be able to change to one of the other predefined custom views.
We have just migrated to Tableau Online and the users with "Viewer" license lost the capacity to create custom views even for themselves (unless I'm missing something). That is specified on the Online license model Tableau Pricing for Teams & Organizations . Too bad they can't even create their own custom views
