1. Please first confirm whether this is a network or proxy issue. Have a look at the Google Action
interface to see whether it displays "Can't update setting, check your connection" or other such message.
If it cannot connect because of network reasons, then when you return to the assistant interface you will
see the spinning loading circle. After loading, the device list will be displayed.
2. If you have confirmed that the network and proxy are normal but the action cannot be linked,
please check whether the account you need to link is for the same app and account. Then check whether
there is a device linked to the account, and whether the device is offline. If there are no online devices,
you just need to add a device and ensure it stays online.
3. If there is a device under the app account and it is online, but action still cannot be linked: Check
whether the device under the account has already activated the Google speaker function.
4. If the issue persists after ruling out the problems above, please provide us with your relevant
information (Google account, app name, app account, app password, linked action name, device ID, time
when the issue occurred) and we will do everything we can to help.
