Graph API 1.0 - Listing lists doesn't return all lists (todoTaskList)

Hi, first time posting here, please let me know if I should be doing something differently! I've searched throughout the internet and couldn't find a reason for this. I've got a couple of users run...

The Microsoft Graph To Do API (v1.0) doesn’t return all task lists users see in the app—special or virtual lists like “My Day” and “Flagged Emails” are excluded by design because they aren’t stored as regular task lists. If users only see these special lists via the API, it’s expected behavior, not a bug. To access all standard personal task lists, ensure proper permissions and user context, and consider testing the beta API or checking for shared mailbox scenarios. Microsoft is gradually improving this, but full parity with the app isn’t there yet.

Thank you so much for the reply MrCharlesJenkins !

I'm aware those types of lists aren't available in the API, but we're talking about "regular" lists that the user has created in the To Do app directly. I've also checked for proper permissions and user context (it works for many other users), and this isn't on a shared mailbox, it's a "regular" personal account, and I've also tried using the beta endpoint with the same results.

Any other ideas?
