Seeded snaps - channel process

Quick question - with seeding a snap package. I know a channel has to be opened (easy) based on stable/ubuntu-18.10 (format), but I seem to remember reading somewhere that it had to be “closed” after to work properly. I cannot find reference to this in the documentation ( I then had a peek at and it too does not say anything about closing it down. Or am I not remembering this correctly?

And then side not - how to kill a channel? (my google-fu failed!)

Thank you all!


Simply ignore this question. For some reason earlier when I was searching the forum I didn’t come across a result for a post I myself had already done! (Arg).
