Help with Dynamic Lighting - Dragon of Icespire Peak Module

Hi, I'm new and need help. I have recently discovered Roll20 and love using it! I am playing a PC in a friends campaign and I am running my own for some others.  I am trying to incorporate dynamic lighting into Dragon of Icespire Peak Module . All of the dynamic lighting walls are pre created. I have added light sources which emit light. I have dynamic lighting turned on in the page.  The player token has visibility and 60ft night vision My players screen is just blank! I have read other posts on this and watched tutorials. On a previous game, I played around doing it myself and it worked fine but doesn't on the module. I know most experienced DM's wouldn't use a module, but I am still new and so is my party. Can anyone help please?

Verify that the token has a check mark next to Has Sight and has your player in the character's controlled by it the Token's controlled by. Check also that you have Fog of War off for the page and that the token is on the Objects layer. Verify the player ribbon is on the page. 

All of those things were as suggested. I have gone over to using the legacy dynamic lighting as that seems to be working for me. Shame as the new system looked like it should function better. 

Updated Dynamic Lighting (UDL) is still in beta testing, and is not recommended for live games in most cases.
