Hello,
I faced the same issue yesterday.
Just after I received my Starlink kit package, I installed it. It worked great (300Mbps/27Mbps/45ms)!
Then, I clicked the update button on the Starlink application. And .. "It's gone!", the router is no longer powering on.
I contacted Starlink support though the web interface and got an answer in 10 minutes : "1 free month and a replacement kit"
Regards from France,
Nicolas
