Dark Mode via States & Variables

Hi there,

First time posting here. I am working on a Dark Mode using States and Variables. I was playing with a few things and had it working, then I guess somewhere along the way I messed it up and can't seem to get it back on track again.

Essentially, I've done the following on a Feedback Master Layer:

- Made a navigation bar with a Light/Dark state

- Created a "DarkMode" True/False variable

- Added a button with a trigger: When user clicks button = adjust variable DarkMode to True

- If variable DarkMode = True, Change State of Rectangle to Dark (Added Dark State)

I can get that all working fine. But what I can't seem to get working is having it carry over to other slides (For example, if DarkMode = True, DarkMode should carry to all slides until DarkMode = False). So on my non-master I tried setting

- Layer to automatically show (Works)

- Turned off "reset initial state" in layer proprties

- Set trigger (on the layer): Adjust variable to DarkMode when Timeline Starts on This Layer if DarkMode = True

Any ideas? Dummy slides added below since my working file is confidential.
