By default, adult channels are not uploaded to the playlist.
To have the channels uploaded to the playlist, you need to go to the Settings (1) section in your personal account and select the Upload to Playlist option in the Erotica (2) box.
The change of value is saved automatically.
Next, you need to refresh the playlist in the player and the adult channels will be available for viewing. If the channels do not appear after refreshing the playlist, you may have hidden this category. Check your sorting.
Please note that some players use their own PIN code for this group of channels. Use 0000 or 1234 as an option.
