| Tasks disappear after returning later | Guest storage expired after 30 days of inactivity or site data was cleared. | Check whether you are in the same browser profile; restore from a saved export or sign in for future account sync. |
| Tasks do not appear on another device | Guest data is stored in one browser rather than automatically synchronized. | Sign in to use account synchronization, or transfer data with a supported export/import workflow. |
| Quick Add chooses the wrong date | Natural-language date interpretation may not match the intended date or time. | Open the task and set an explicit date and reminder after saving. |
| Task did not appear in Today | The task may have another due date, a different status or an active filter. | Inspect due date, status and filter settings; reset filters to locate the task. |
| Browser reminder does not arrive | Notification permission or browser/device background behavior can restrict alerts. | Enable permission, test a low-stakes reminder and use a second reminder for important deadlines. |
| Recurring task is scheduled on an unexpected day | Monthly boundaries, custom rules or completion timing may affect the next occurrence. | Review recurrence configuration and explicitly check the generated next due date. |
| Task stays in the wrong Kanban column | Its saved status may not match the column or an update may not have persisted. | Reopen the task, verify status and reload after confirming the save. |
| Dragging a card does not work on mobile | Touch gestures, scrolling or small-screen controls can interfere with drag actions. | Use available task-edit status controls and try a steady press-and-drag. |
| Checklist progress appears misleading | Progress reflects item completion rather than time or effort needed. | Review the remaining steps manually, especially items with dependencies. |
| Search returns too few results | An active tag, status, date or project filter may restrict matching tasks. | Clear filters, shorten the search phrase and try a different relevant term. |
| Critical tasks dominate the view | Too many tasks may have been assigned the highest priority. | Reassess urgency and reserve Critical for important high-consequence items. |
| A task appears duplicated | The same item may have been imported, duplicated or entered twice. | Check titles and creation details before archiving an extra copy. |
| Imported CSV has wrong dates | Source columns or date formats may not map as expected. | Inspect field mappings and standardized date formats in a small test import. |
| Imported TXT misses some items | Blank rows or incompatible text structure can affect parsing. | Use one clear task per line or documented Markdown checkbox syntax. |
| JSON import does not restore expected data | The JSON structure may not match the supported importer schema. | Use an export created by the same tool as a reference; check errors before overwriting other data. |
| Excel export looks different from on-screen view | A spreadsheet exports tabular fields rather than the visual board or calendar. | Use PDF for a fixed reading layout or JSON for a structured backup. |
| Printed PDF omits interactive features | PDF is a static document, not an interactive planner. | Keep the app or JSON backup for editing and use PDF only for reference or printing. |
| Changes made offline do not sync immediately | The server is unreachable or account sync is pending. | Reconnect, check signed-in status and verify updated tasks appear on another device before clearing local data. |
| Guest items seem missing after sign-in | Workspace migration or account selection may not match the expected state. | Confirm the signed-in account, check current lists and restore an export if needed; avoid clearing storage during transfer. |
| Task data disappears in private browsing | Private sessions can delete browser storage when closed. | Use a normal browser profile and export or account sync for important tasks. |
| The productivity score seems low despite major work | The formula counts task completions and recent activity, not full impact. | Judge meaningful outcomes manually and use the score only as a secondary signal. |
| Calendar becomes overloaded | Too many tasks may share unrealistic due dates. | Spread preparation steps over earlier days and reassess capacity. |
| Completed tasks clutter active lists | Completed entries remain visible with current filters. | Switch status filters or archive completed items without deleting records. |
| Notifications feel excessive | Many reminders or recurring alerts may have been enabled. | Reduce reminder frequency, adjust permissions and keep only actionable alerts. |
