Hi - newbie to Lectora here, with several years' Storyline experience.
I want to create a mobile phone portrait view that is several thousand pixels long. This works fine in 'RUN' mode, but when I view it on an actual phone, the whole project is shrunk to the height of the phone browser.
Have I made a schoolboy error? Or, am expecting too much?
You should check your publishing settings. "Scale content to fill mobile device view" might have this effect when the content is scaled to match the height of the screen.
