Addressables to reduce WebGL load time

I’m trying to decrease the load time of a WebGL player. In order to do this, I’m trying to use Addressables so that I have low res textures at load time but then asynchronously load the high res texture. However, I get a “Your browser does not support any of the required graphics API for this content” error when trying to load it – which I did not get prior to using Addressables. Any thoughts?

Am I just going down the wrong path using Addressables?

What browsers did you try it on? What Unity version do you use?
