My Day sync issue between To Do and Tasks by Planner and To Do (Teams)

I am seeing an issue where tasks added to My Day in To Do (in either the web app or Outlook) don't appear in the My Day list in Tasks by Planner and To Do, however tasks added to My Day in Tasks by Planner and To Do do appear in My Day in To Do, so it appears they are supposed to be linked. Is there some setting somewhere that I need to turn on?

I like the interface for composing my day better in To Do because it combines To Do tasks, flagged emails and Planner tasks all in single view, but I like the Tasks by Planner and To Do interface better for actually working with the tasks because the task editing interface is much more detailed, especially for Planner tasks.
