Continuity mistake: Peter is in Lara Jean's kitchen, wearing a jacket. Her dad comes home, he and Peter shake hands, and in one brief shot Peter is not wearing a jacket but a plain short sleeve top. Angle changes again and the jacket is back. (00:39:00 - 00:40:15)

Continuity mistake: When Peter is talking to Lara Jean about the letter when they are in the diner, the straw in Lara Jean's glass changes position between shots, and changes from white to clear. The cherries also disappear or move.
Continuity mistake: Lara Jean is baking cupcakes at sometime in the day (we know this because its light outside). Peter then comes to pick her up for a party. Once they are at the party, Peter makes LJ change her lock screen to him and when she asks what his is, he shows her, but we see on his screen that it is now 12:18am. No way it took them 6 hours to get to the party.
