Thank you for posting your question in the Microsoft Q&A forum.
Regarding your issue, may I kindly ask a few questions to help understand your issue better:
- I saw that you posted your question on Teams under the Business category so to better support you, could you please confirm whether you're using a Home account (e.g., Gmail, Hotmail) or a Business (typically associated with a domain name like your company or school) account?
- Are you experiencing this issue on Teams desktop, Teams on the web?
- Have you checked Planner on the web at https://planner.cloud.microsoft to see if the data appears there?
- Have you tried clearing all filters in Teams Planner to ensure no tasks are being hidden? Also, please check if the tasks are marked as "Completed" or have been moved to a different bucket.

Hope to hear back from you soon.
