What is a necessary step after modifying a view subscription for it to take effect?

After modifying a view subscription in Tableau, saving the changes is crucial for the modifications to take effect. When you adjust settings such as the frequency of the subscription, the recipients, or the content of the view, these changes need to be actively saved within the system. If the changes are not saved, the previous settings will remain in effect, and your updates will not be implemented.

Refreshing the dashboard, while important in some contexts, does not apply here because it pertains to updating the displayed data rather than saving settings. Notifying stakeholders might be a good practice for communication purposes, but it is not necessary for the changes to technically take effect within the subscription settings. Deleting the old subscription is also unnecessary as modifications are applied to the existing subscription rather than the creation of a new one. Thus, saving the changes is the operative action required to ensure that your modifications to the view subscription are successfully applied.
