That's curious. I was just notified of the last post which reminded me that I needed to update my status after installing QBD 2022. I have no idea why, but after installing 2022 my To Do lists started working again...after years. I had to install 2019 on another computer which I would log into periodically to update the To Do's that came do and clear them out. In parallel I created an independent ToDo list of my own to replace the one in QB till it was fixed. A completely unacceptable workaround.
