+Original issue: https://github.com/TeamNewPipe/NewPipeExtractor/issues/10774
+
+YouTube added a filter system for playlists, allowing users to only see shorts/full
+videos.
+
+When shorts filter is enabled or when there are only shorts in a playlist, YouTube
+return shorts UI elements instead of standard video ones, the ones that are also used
+for shorts shelves in searches and suggestions and shorts in the corresponding channel
+tab.
+
+Since the reel items dont include upload date information you can circumvent this new UI
+by using the mobile client. But that may change in the future.
