I'm developing a company dashboard, wish MS To-Do is part of as a widget, and there is no value if I can't sync task order between tools such as MS To-Do, Outlook, or To-Do mobile applications.
As seen on Outlook Task REST API documentation, I could do that, but that will be deprecated later this year (source). Both outlook web and MS To-Do online seem to be using that API.
So the order can be fetched and patched through the field "OrderDateTime".
The main idea is to add this missing important field for our apps, into GraphAPI for both listing (GET) and updating (PATCH), which currently is not working.
