Yes - this is what I came here to report. First, Ai Assistant Project Builder keeps creating Subtasks as To-dos (even when I specify SUBTASK) and there is no way to CONVERT them to Subtasks or link them as one in any way. So we spend a lot of time copying To-dos into Subtasks because they make more sense as Subtasks that have their own To-Do steps to take.

AI Assistance is also not creating referring tasks, only regular tasks.
