glTF mesh is being imported inside out

Questions

I’ve made a model in Blender, which looks fine, but if I export as .glb and upload it to the sandbox, all the faces are inside out:

I have already googled around and found out that some normals needed to be flipped, but even after flipping the normals so that the blue side is facing outwards, and after selecting all vertices and recalculating outside, it still appears inside out in the sandbox.

Any idea what’s happening?
