1. Computer system or browser problem: The intelligent programming typing keyboard may be restricted by the computer system or browser, which may prevent it from popping up. At this time, you can try to change the browser or clear the browser cache, or check whether the settings of the computer system have restrictions on keyboard input.
2. Network connection problem: the intelligent programming typing keyboard may need to be connected to the network to be used normally. If the network connection is unstable or disconnected, it will lead to the failure to eject. At this time, you can check whether the network connection is normal, try to reconnect the network or change the network environment.
