Hello,
Thanks for your Patience and Apologies about the Inconveniences caused!
Please consider checking out the Official Documentation on the Revolution Slider's Layers Responsive Setup: https://www.themepunch.com/revsliderjquery-doc/responsive-setup-2/ . You will need to add the following attributes to the Layer:
data-width="['800', '800', '600', '400']"
data-height="['auto', 'auto', 'auto', 'auto']"
to define the Size of your Layers according to the Device Sizes.
The reason for delay in replying to you Support Query was because it is related to Customization of the Revolution Slider and is Out of Item Support Scope according to the Item Support Policy: https://themeforest.net/page/item_support_policy . While we are always here to provide you with all the Help you need with the Features included with Canvas or any bugs, but we cannot provide you with feature specific Support for Custom Features or Design Integrations.
Hope this Helps!
Let us know if we can help you with anything else or if you find any further issues.
