No firmware update recently. What's the notification to let you update it? Please inform your login email of the app, technicians will check, if it's private you can start a conversion with us.
 
Did you guys put your phone close to the Hub when it's updating?
 
There is no firmware update of the Wifi Hub, it maybe an app bug. You guys don't need to update the firmware of the hub, our software technicians will fix that bug soon.
