Thanks so much for the quick turnaround on this! I think the overall changes look good to me! I'm not sure what might be happening in the snapshots tests though 😅

Thanks! :) Yeah me neither, I think I'll have to figure out what's going on locally with running tests on a future contribution if it comes up again. Hope I can get this through by end of this week! :)
