My tasks are missing (Today counter shows a count but no tasks appear)

This happens when those tasks have a future start date. They're scheduled to begin later, but they're still due today, so the counter sees them.

Fix: Use the clock-shaped button on the sort bar to toggle visibility of scheduled tasks. The "missing" tasks reappear. Your tasks aren't actually missing. They're hidden because Smart Scheduling is keeping them out of view until their start date arrives.
