Problem with adding lists from Word or One Note into To-Do correctly

Hi, i have a problem with adding lists to my To-Do. When I copy a list from OneNote to a list in Microsoft To-Do via my laptop, a new item ist austomatically created in the list after an Enter character, so that copying a list pastees them one by one into To-Do. However, when I try to do this via my smartphone, only the list is inserted without creating individual elements. Does anyone here have any idea how I can also create individual elements by copying a list with my smartphone?
