I'm using a O365 Groups data source to look up users in a department. The results in the drop down, which is User Display Name, are apparently random, or maybe sorted by ID. It makes for a really ugly lookup. Having sorting options would be really, really nice.
Anne, thank you very much for posting your feedback for our review. Due to very low votes, we will not be adding this request to the near-term backlog. We are also focused on other highly requested features such as Form Participant permissions, Repeating sections re-usability, etc. Please keep the feedback coming as it is critical for our longer-term planning.
