VLC 3.2.8 for iPadOS
iPadOS version: 13.4.1
Adding videos to existing playlists is not possible.
How to recreate the bug:
- tap on the Edit button in the top-right corner;
- select video;
- tap on the "Add to Playlist" button in the bottom-left corner;
- tapping on an existing playlist does nothing, except switching on and off the edit mode in the background;
- the only options available are the Cancel and the "Create a new playlist" buttons.
