Resolve common issues
為什麼內容包無法下載？
Why can’t I download a content pack?
確認裝置已連上網路、已登入帳號，且訂閱狀態有效。若下載中斷，請重新開啟 App 後再次嘗試；已完成的內容不會重複下載。
Check your connection, sign-in status, and active subscription. If interrupted, reopen the app and try again; completed content will not be downloaded twice.
如何調整聽力播放速度？
How do I change listening speed?
在聽力題目的播放器中選擇語速。設定會保留在目前裝置，可隨時恢復正常速度。
Use the speed control in the listening player. The choice is saved on the current device and can be reset at any time.
學習進度沒有同步怎麼辦？
What if my progress does not sync?
確認兩台裝置使用同一個已連結的帳號，並保持網路連線。離線作答會先保存在裝置上，恢復連線後再合併。
Confirm both devices use the same linked account and are online. Offline activity remains on-device and merges after connectivity returns.
如何恢復訂閱？
How do I restore my subscription?
前往 App 內的「設定 → 訂閱」，選擇「恢復購買」。請使用原本購買訂閱的 Apple ID。
Open Settings → Subscription in the app and choose Restore Purchases. Use the Apple ID that originally purchased the subscription.
如何刪除帳號與雲端資料？
How do I delete my account and cloud data?
前往「設定 → 帳號 → 刪除帳號」。刪除帳號不會自動取消 Apple 訂閱；請另外在系統的訂閱管理頁取消續訂。
Open Settings → Account → Delete Account. Deleting the account does not automatically cancel an Apple subscription; manage renewal separately in system subscription settings.
