We have a new approach to contextual help that will allow your employees to get context sensitive help inside of Salesforce Lightning, Classic, and any other cloud application.
This is done through the use of the ScreenSteps Browser Extension.
If you would like to try it out, please contact [email protected].
The contextual help ScreenSteps app that is available for ScreenSteps in the AppExchange is deprecated and won't receive further updates. It will only work with Salesforce Classic, not with Salesforce Lightning.
You can still embed your ScreenSteps site as an iframe inside of Salesforce Lightning, but the AppExchange ScreenSteps app will not work.
For contextual help you should use the new ScreenSteps Broswer Extension.
