Sorry, cloud control does not support one-click closing of all activities. I'm not sure if your ibrroker supports multiple actions. If supported, it is recommended that you copy the API command to close each activity into the settings
X1 can be used as a virtual Bluetooth keyboard. When adding a device, select Bluetooth mode and select other for the brand. After downloading, you also need to select Bluetooth related options in the device settings, find the sofabriton device, and click to complete the pairing.
Thank you for your suggestion. I will feed back your comments to our R&D center to evaluate the feasibility and consider whether to change it in the next update.
