Accidentally pitched my yeast in really cold cider, should I pitch another batch of yeast?

So made a gallon of cider yesterday as a test batch, and I wasn't thinking moving too fast and accidentally pitched the dry yeast (D47) into it. I thought maybe if i give it some time it'll bounce back but it's been over 24hrs and really haven't seen much activity inside except maybe damn near microscopic bubbles.

Wondering if I should just re-do it with more yeast or would that mess up the flavor and I should just ride it out and see how it goes?
