A recent change means when uploading a GPX course on Safari on iPad (probably when creating a new course in other ways as well) the course creation works …
… BUT the design of putting the ‘Save’ and ‘Send to Device’ buttons at the bottom of the page and not calculating the page height correctly means the buttons are off the bottom of the screen with no scroll bars. You need ninja-skills to zoom out, spot the button and click-to-stop-the-re zoom to be able to access the buttons.
Layout for the course points and majorly the elevation profile is also messed up big time!
I’m sure someone in the whole of Garmin has these relatively popular bug screen devices for course planning, please test and update!
