Just to clarify, my issue with the shop is simply that I bought the bike just a couple of months ago (admittedly I've ridden 900+km in that time) and now the chainring is gone. If you saw the video of how lose the chainring got - which I am sure is not "normal" under any circumstances, I am wondering if I'm in any sort of position to ask the shop to replace parts effectively under warranty because the wear may have been caused by the dodgy chainring.
My take...
If it happened in the first few miles after riding the bike out the shop, or on your first ride, yes take it back, get the lockring tightened. But after 500 miles of hard riding offroad, it's down to you to check for anything coming loose.
That doesn't mean the shop won't help you out a bit to keep you as a happy customer - although them sending you the quote suggests they might not here.
After 400 miles on my new eMTB, I generally agree with the views above. Keep the transmission tough, cheap and no need really for 12 speeds.
So I'm in the same situation with my 12sp GX/NX, but I'll wait until the cassette has worn out before switching to something else. 12sp GX chains are £20, sometimes cheaper, chainring I expect to last as long as the cassette if not longer.
