I also have issues with task text not always getting saved if I make edits to it on desktop (Windows), AND some weirdness where sometimes a note with tasks will appear blank but if I duplicate it, the copy does have the tasks showing up. The duplicate workaround is not great but at least there is a workaround. Losing edits is a big problem and I'll probably switch back to bullet points instead of tasks or find another task management app because I worry I'm forgetting one of my edits when I try to recreate the work.
