Previously in the old view the suggestions displayed when clicking in the field Sprint displayed the sprints that you last interacted with first.
Now, with the new view, that's not true.
See the recording showing the comparison of results: Sprint sugestions - Old vs New.mp4
The Sprint field does not restrict the results per project (issues can be added to any sprint of each project). The suggestions displayed in the old view are helpful to reduce the incidence of adding issues to wrong sprints. For example, if a user works only on a project, the suggestions will point to sprints from that project only.
The suggestion is to have the new view display the suggestions just like the old view did: by order of interaction.
