@TVP,
I’ve merged your post into an existing topic where you can click the title to scroll to the top and vote by clicking the purple Vote button.
When viewing a subtask, you can type Tab+P and make it a member of a project, or do so with multi-select, as a workaround. The side effect is that it will become also a top-level task in that project. If that’s undesirable, you can create a Hidden Subtasks section, drag it to the bottom, collapse it, Save view, and then make sure all the subtasks are homed to that section within the project.
Another workaround would be to consider a different approach for My Tasks. One I recommend is here:
Thanks,
Larry
