When you received one or many layers that came to you from someone else or from other sources and has many red exclamation point(s) next to each layer.
I followed the instructions that came with it but didn't get what I wanted.
One tip states, "If you have several layers that reference the same data source, that need to be fixed, you can repair the links one time in the Contents pane and ArcGIS Pro automatically repairs other broken layers. For example, if you have several feature classes stored in the same geodatabase, and the geodatabase has been renamed. Click the red exclamation point next to the layer to open the Change Data Source dialog box and browse to the correct source."
So did all the shapefiles in your aprx project have a red exclamation point and do they all point to the same folder location? I believe all the shapefiles would need to reside in 1 folder for your 1 click workflow to work.

indeed - another step backwards for the (still IMHO pre-beta) software that is ArcGIS Pro.
I do wonder how these decisions to remove features are made - old desktop had the perfectly good "Repair" option that, well , did the job, but that is now gone.
