If a guest tells you (or you notice in your message log) that Suzy gave an incorrect or outdated answer, go to Dashboard > FAQs and update the relevant entry - or add a new one if none existed yet.
There's no waiting period: the fix applies to the next guest message immediately.
Some properties can also text a correction directly to Suzy's number and have it saved automatically - ask your onboarding contact whether that's turned on for your property yet.
