have had a scammer reach out to me on the first day and the app has no way to report it ridiculous. Not only that I get an error code if I try to go anywhere but the news feed. I don't know how anyone could trust this app after my experience super pissed off.

No obvious way to find an item on the website in the app. No obvious way to vote for an item.
