Shadergraph UV scrolling textures not updating

Hi guys

I have a very simple Shadergraph test shader that doesn't appear to function as expected. Essentially I can't seem to view any amount of UV scrolling within a shader even when simplifying the shader down as much as possible. I can tell that the texture is using the scrolling UVs as the preview shows the texture moving over time but when I connected the texture to the shader it doesn't seem to receive any scrolling.

Is this a common problem and am I missing something simple?

From what I can tell I should be seeing this movement within shadergraph based on this video

 

Just curious if you ever figured this out. I see the scrolling within the editor for something as simple as the particle texture but not any of my own textures. Is there something about the dimensions of a texture that influence this?

 

I've seen this happen before, but I've never been able to reproduce it reliably. The texture always pans in the scene view (assuming animated materials are enabled) and in game, so it appears to just be a bug in the graph preview.
