Hello

the update is showing as available to download and install in the app. I've attempted this multiple times with no joy. I've even manually rebooted the deco p9's. 
 

each time I go to the app and click on the "Update Deco" button it tells me the update is still available with an install button. 
 

please can someone from the tp-link team advise on corrective measures to install the new firmware. 
 

thank you
