I’m having some trouble with deleting devices from an application on meshed-handler. Adding the devices is no problem (the naming schema is within TTN spec), but if a device is removed via the console or backend, the success message is shown. However when the page is refreshed the device is still within the device list. Same goes with the backend CLI, the device is successfully deleted but if the list of devices is queried again it still remains. Any recommended troubleshooting steps?
