404X stuck blinking green

Finally received the new 404X LTE M1.
Using mobile app

Stuck blinking green and “Connecting to the internet via cellular”

What procedure do I follow next? Old school Boron happily breathing cyan right next to the new one that refuses to connect.

Thank you

I did a factory reset on the Boron and now was able to connect. Not sure why it needed that but that is the only way I was able to get any of them to connect.

Mind DMing me the device ID? Glad a factory reset got it working but I want to see if there’s anything unusual going on in the logs.
