CoS Number change (outside UK, SWV)

Hey guys,

My employer had to change the CoS number on my last visa SWV application because they were told it wasn’t “defined”. Apparently in changing it, they added it to the last application which I was told to withdraw from because “I can’t change the CoS mid-application and I have to start a new application”

Second application around, with expenses coming out of my pocket, home office says now I can’t use the new CoS because it was used in the last application.

WTF? Do I absolutely need to start a new visa application every time the CoS changes?

Thanks for all the help, I’ll have a proper timeline summary of this complete mess to share once I’m approved.
