Thanks @rwrenner_esri .
Hi @MariaBonderupPedersen ,
I can confirm it is a known limitation that you can only select/embed public surveys belongs to your org in the Survey widget currently. You can use the Embed widget as a workaround for now.
We have an issue in the backlog, please feel free to raise an enhancement ticket to Esri Support to help prioritize this work.
I will contact the doc team to remove ambiguous from the doc topic.
