I checked my pets into the resort, but I want to check one out. There;s supposed to be a button on the pets page, but I can't find it anywhere.

it takes a while for the pets page to update. it can take an hour or so for the "this pet is in the resort!" message to appear, and another hour+ for it to disappear after you click "remove."

Okay, thank you! I guess I'll keep waiting.
