Frequently Asked Questions 常见问题
How do I reset a Push Key? 如何重置推送密钥？
You can reset the Push Key for a selected device or device group from the Push Key management screen in the MeowPush app. The previous key becomes invalid immediately. If you suspect that a key has been exposed, reset it as soon as possible to prevent unknown senders from delivering notifications to your devices. 可以在 MeowPush App 的「推送密钥」管理页面中重置选定设备或设备组的密钥。之前的密钥将立即失效。一旦察觉到密钥泄露，您应该尽快重置密钥，防止未知发送者投递通知到您的设备。
When should I use device groups? 设备组适合什么场景使用？
If you use multiple devices, you can group them for different needs and change the devices in each group at any time. A push request sent to a device group is delivered to every device in that group. For example, you can group devices by purpose, such as “Work” and “Personal,” or by platform, such as “Apple” and “Android.” 对于有多台设备的用户，可根据需求将设备分组并可随时调整组内设备。发送到设备组的推送请求将会触达组内的所有设备。例如，可按「工作」「个人」等用途分组，或「Apple」「Android」等平台分组。
Why does a notification read on one device remain on other devices in the group? 为什么设备组内某一台设备已读的推送，在其他设备上依然存在？
Because of platform limitations, on most mobile platforms the app can only guarantee that read status is synchronized and notifications are removed from Notification Center while the app is in the foreground. Read notifications may remain in other situations. Remote read-state synchronization is currently supported only on HarmonyOS. 受制于平台限制，对于多数移动端平台，App 仅能确保在前台时同步已读状态并在通知中心移除它们，其他情况下可能无法移除已读通知。当前仅 HarmonyOS 支持远程通知已读。
What is push usage? 推送用量是什么？
Under our fair-use policy, each account receives a recurring monthly push allowance. It represents the number of push messages the account can receive during that period. If you need a higher allowance, contact us or wait for higher-quota plans to become available. 出于公平使用原则，每个账号都分配了周期性（月度）的可用推送额度，它表示账号在这个周期内可以接收推送的消息条数。如果你需要更多额度，请联系我们或等待后续退出的更高配额计划。
