00:00:00,000 --> 00:00:05,700
Step 1. For missing tasks, select All tasks to clear filters, then check Completed and the lists.

2
00:00:05,700 --> 00:00:11,500
Step 2. Example: an invalid JSON backup is rejected. Your saved tasks are not changed.

3
00:00:11,500 --> 00:00:16,000
Step 3. Example: unreadable sample storage causes Storage needs attention.

4
00:00:16,000 --> 00:00:21,100
Step 3. Export the raw stored data before any reset. It may need repair before import.

5
00:00:21,100 --> 00:00:27,033
Step 4. Example: blocked storage causes Unable to save. The failed change is not saved.

6
00:00:27,033 --> 00:00:33,000
Step 4. Export saved tasks and keep unsaved text separately. Fix storage settings, then retry.

7
00:00:33,000 --> 00:00:38,800
Step 5. Reset demonstration: only this recording’s sample storage is cleared, then the app reloads.

00:00:38,800 --> 00:00:45,667
Step 5. In normal use, export first and clear this site’s data in browser settings. Then import a good backup.
