Microsoft To-Do Tasks Disappear Randomly Across iOS and PC
Users of Microsoft To-Do experience tasks and subtasks silently disappearing after editing on one platform (PC) and checking on another (iOS), with no error message or recovery path. Cross-device sync failures also prevent tasks added to 'My Day' from appearing on mobile. This data loss behavior in a task management tool undermines trust in the product for anyone relying on it for daily work.
