Hi 
I have a deco mesh set up with 1 M5 deco connected directly to a fiber modem and 2 additional X20 wired to it 

I have an issue after performing a firmware update to the M5 Deco. 

every time going to the application it will show that there is a firmware update pending and will take me to that screen. 

the issue is that the upgrade button doesn't work and I cannot go back to the app. 

I have tried to reconfigure my network by doing factory reset. 
I have tried to update the App on my phone and Mac 

any Idea what I can do ?
