New Stream Web Part - Source > Folder > From Sites > Only shows recent shared libraries

We do understand that picking up the right set of videos is getting painful, especially when the picker is not functioning the way it should have been. Thanks for highlighting these as this helps me note down the gaps and prioritize them accordingly. We are currently investigating as to why is the picker not showing all the sites and just limiting to 12 recent ones. Additionally, the folder picker is designed in a way to show folders only, we are also starting to explore different ways for showing information on folder content inside the picker for user awareness.
