Every search now asks which marketplaces to run on. Pick Facebook Marketplace, OfferUp, or both. Open a search you already have and you can add OfferUp to it without setting anything else up again.
Alerts say which marketplace the listing came from, so you know where you are messaging before you open it. Keywords, price range and instructions all work the same on both.
Searching OfferUp is an add-on to your plan rather than part of Pro, so if a search shows OfferUp locked, that is what it is telling you.
