Hi Yvette,
Thanks for your feedback.
If you haven’t tried it yet, I recommend using the Microsoft To Do app on your phone (iOS/Android). The date picker there usually supports faster year scrolling.
Alternatively, you can create the task first, then edit the date by typing the desired date directly (e.g. 06/12/2030) instead of using the scrolling calendar.
I understand the trouble this problem has caused you. Since we are not Microsoft employees, but participants in this community, you need Microsoft to fix it to roll back in subsequent system updates, the development team is considering adding a quick year selection feature. I suggest that you may need to submit your problem in the Feedback Center.
If you need further assistance, I’m always available.
Best regards,
