How to get watch later playlist details after September 12th?

Question

Today, on YouTube\'s revision history page it is stated that

The channel resource\'s contentDetails.relatedPlaylists.watchHistory and contentDetails.rel

Answer 1

The changelog confirms that the watch history and watch later playlists return empty lists. Unfortunately, no alternative is mentioned.

September 15, 2016.

In addition, requests to retrieve playlist details (playlists.list) or playlist items (playlistItems.list) for a channel's watch history or watch later playlist now return empty lists. This behavior is true for the new values, HL and WL, as well as for any watch history or watch later playlist IDs that your API Client may have already stored.
