Why does the App always show that the device is offline, and how does it automatically recover in a second or two, but the thirdpart shows that the device is still offline?

Dear user. This is because after the device automatically comes back online, it can automatically connect to our cloud server. However, third-party smart speakers have their own independent cloud servers, and our devices cannot be automatically connected. We suggest you to remove the devices from the App (device removal method: enter the App and enter the device control page, click the icon on the top right corner, then click "remove device" on the bottom of your screen) and add them again with a stronger and more stable network (for example, the personal hotspot on your phone). When devices go offline frequently, they're unable to be controllable in Alexa/Google Assistant/IFTTT. If the offline issue persists, you can provide feedback in the feedback channel of the App.
