The iOS version does not seem to accommodate a dynamic screen for the mobile device you are using. It cuts off part of the desktop screen when used in landscape mode. It does not adjust for notched devices either. Any word on updating this?
Yes, unfortunately the mobile Viewer is somewhat lacking in functionality and UI. However, we will definitely improve this in our future updates since we plan to release an improved version of mobile Viewer which also includes a full-fledged address book.
