I have two identical particle electron boards both using same 3rd party sim card and loaded with device os 1.0.1.
They all work just fine connecting to server however one of them is not able to flash over cloud while the other one has no issue with that.
I tried flash using particle CLI on visual studio code by pressing ctrl+shift+P then chose Particle: Cloud flash
I did change the name of the target for each board by ctrl+shift+P then Particle: Configure Project for Device .
Is there anything I have to look at?
