Glass Shader not working in 4.12.(3)

Hey all,

UPDATE: 4.12.4 installed, same thing.

I’ve recently converted via copy a project of mine from 4.11 to 4.12, but I’ve noticed that the glass reflections are no longer working.
I’ve also tried to create another shader in a new project but got the same results, am I missing something here? Please see images attached.

4.12 (no reflections on the glass)

4.11 (reflections working)

Thanks all!
