As we continue to improve SharePoint, we’re updating two more list types. Links and Announcement lists now have improved page performance, responsiveness and accessibility, just like your other lists.
Last year, we introduced two new web parts — Quick Links and News. These provide even more capabilities to share dynamic information about related sites and team updates on any page to any device on a SharePoint site. For most scenarios, we recommend the use of Quick Links and News.
Today’s announcement is not intended to replace Quick Links or News but rather to give users of those lists a more consistent experience with the rest of SharePoint.
Links and Announcement lists are not supported by the Lists web part. If you need to add links or updates in a web part on a modern SharePoint page, we recommend the Quick Links and News web parts.
Currently, these lists automatically fallback to classic mode. This update will eliminate the need for auto-fallback. Administrators can choose the classic experience for Announcement and Links lists in advance of the rollout by implementing the steps in this support article, Switch the default experience for lists or document libraries from new or classic.
