Offerup cancelled item after I sent item & clicked shipped! No usps updates. Help!

New Member
Last day to ship app said time was extended, although I still had the day left. I shipped my item to buyer that day, messaged her I shipped it, and click shipped. App sent message to us saying i shipped it. A few hours later it cancelled the sale, but if shipped would go through.
Neither of us knew why it cancelled. 2 days later I checked tracking, and said was still pending. Now 5 days and still says its pending. I have no idea what's going on with the package, or why t was cancelled after knowing it shipped, and now no tracking.
How can I get help for this? Anyone know what happened here? I see no contact info directly to offerup to ask.
