I tried cross-posting from within the app, but the results were not what I expected when compared to the Lemmy desktop UI.

Cross-posting using the Eternity app yields this result: https://sh.itjust.works/post/8099344

• Post URL links to itself (not very useful)
• Post body contains only the name of the original community with no link or content

Cross-posting using the Lemmy desktop UI yields this result: https://sh.itjust.works/post/8144232

• Post URL links to the article (actually useful)
• Post body contains a link to the original post and quotes the content of the original post body

Edit to add tags: “cross post” “cross-post” “crosspost”
