You can deactivate a Feedback widget or Survey by switching the status from Active to Inactive in Hotjar.
For the Feedback tool, this switch is under the Status column on the list view. Click on the toggle with the checkmark to turn off the Feedback widget.
There is a delay between Hotjar and your live site
Removal of the Feedback widget will not occur immediately. There will be about a 1 - 3 minute delay before the widget is turned off/on.
Keep in mind that setting up Feedback is part of the on-boarding process, so it is common a widget was created if the onboarding prompts were clicked through.
