I have Adobe Captivate 2017 and am new to the software. I watched a training on Adobe 8, but I am still experiencing some roadblocks. Particularly, when I switch to a mobile view (iPhone or tablet) from desktop view the layout is off. When I change the layout to fit a particular mobile view, it also changes my desktop view. How do I prevent from this happening? I would like to work on a slide and then modify each mobile view as I go along. Any assistance would be greatly appreciated.
