NavMesh Null error when Previewing world on browser/mobile

Hey! I'm seeing a weird issue where my NavMesh works perfect when previewing in the editor, but when testing as browser or mobile preview the NavMesh cannot be found. I'm seeing the exact same when testing out the NPC Examples tutorial as well as the Chop n Pop template world.

Anyone seen this before and have any pointers?

I see there is a 2 year old post with something that sounds similar but can't confirm if it's the exact same error. https://communityforums.atmeta.com/discussions/dev-unity/navmesh-not-recognised-in-il2cpp-builds/1199692

Hello! 

I found a post that's more similar to what you're experiencing here: Navmesh on Mobile | Meta Community Forums - 1309991 

Have you tried testing opening the preview build and testing in Browser?

Ah thanks! That thread helped. So in the editor and when playing a published build in the store, the navmesh works. 
But when launching a browser or mobile preview from the 'Preview actions' from the editor, NavMesh does not load. As said in that thread the workaround is to just publish your build and test in live.

Cheers!
