@victor @squeevening Hi Victor, I have an update for you on this.
It turns out that the reason why you're seeing two different treatments for posts shared to Flipboard from Mastodon is that it depends on how that sharing happened. Our web bookmarklet properly preserves the Mastodon link along with author attribution, etc. But this is broken in our beta iOS and Android integrations.
We just shipped a server side hack to fix this immediately. A more elegant fix to the clients will ship soon.
