Word on Mobile supports two types of views when rendering your document. Both views are useful and serve different types of use cases. Choose which mode is best for you. At any point, you can switch between the views by clicking on the Mobile Phone icon on the top.
Mobile View: The Mobile View lays your document to make use of the smaller screens of your phones and give you the best reading experience. This view however does not render certain objects like Ink (signatures) and Shapes and can cause loss of context.
Print Layout View: The Print Layout View is the more classic view that makes your documents look like if they were to be printed. In this view, you will have the benefit of seeing the documents as they appeared on your PC. This view will render all your objects without any loss of context. But on the mobile, you might have difficulty reading the content of your documents
