When displaying a slide in the Slides View window and using the Slides View window controls to change the magnification and adjust the positioning of the items on the slide, the settings affects the underlying map and all the other slides.
Hi Klaus. Thank you for your post. This feature is as designed. The slides do not work independently of one another, so by changing the zoom/positioning, the rest of the slides mirror that behavior as well. I hope that this helps to clarify things. If you would like, feel free to submit this as an idea so that our team can take this into consideration for future releases.
