If you do have YoLink App account, there might be three reasons.
1, Google Home has a new version, please kindly update your Google Home.
2, Please do not log in to your Google account in two phones. If you open your accounts in two phones at the same time, there might be many unknown conditions, like a crash.
3, Please kindly make sure your network signal is strong. If the signal is too weak, it will take more time for loading, and please kindly wait a while.
