If your tweak includes website layout changes, chances are that your mobile view may be affected after making these changes. Retouching your website's mobile view is known as responsive design. This is a time-consuming process which involves layout testing across various devices and resolutions, and as such, it cannot be included as part of the same 1-hour tweak.
If you've purchased a single tweak, in order to make these changes, we may need to treat the mobile fixes as a separate tweak. If you are subscribed to our service, you can simply submit a request for the mobile fixes, as your next task.
