chain on Nearly New bike Slipping

[cutler26]

I've checked the wheel and hanger and they both seem fine, I've loosen the derailleur on the hanger and repositioned it to reduce tension. I have also gone through the rear derailleur cable adjustment for further fine tuning. I have rode for about ten miles today and the issue is still there although it's less frequent now.

Change the chain. If the link split, there could be damage.

It was the master link that split, do you think replacing that link would be suitable?
