I have set the playlist thumbnail in youtube to be the Dolphin video in the playlist. However, ARVE pulls the thumbnail from the second video in my playlists. The example above is just one case. This happens on all of the videos on the site. Just purchased your plugin, so hope this can be resolved easily.
You can set a thumbnail specifically for a playlist?
What you can do is use links like you get when you click share while playing a video in the playlist, these links include the video and the playlist, they start with the referenced video in the playlist. So the dolphin video is the first in the playlist anyway so you can just use this URL https://youtu.be/kNV-LLnfNPg?list=PLz8Z8h1MloaOg_pknSIr4Vf1_LAyh_z3l it will pick the thumbnail from that first video. Not sure why it picks the 2nd with just the playlist URL.
