This ^ has been my experience. I use bullets and todo's heavily in my workflow, and find that Evernote updates randomly break bullet and todo functionality.
Another issue is that adding a todo to a bulleted line now adds horizontal padding to that line, so I can't see as much of my todo-list at once. I would love the option to disable this padding.
It's gotten frustrating enough that I've started to post on Evernote forums.
