Fab viewer is much worse than SketchFab Viewer

Hello, I’m tearing my hair out, rhaaaaa.
I don’t understand why my 4k textures are showing up as 1k on the Fab viewer.
I reload the 4k ones and, magic, it goes back to 1k.
If the quality of my model looks bad, no one will buy it.
I think it’s because of model theft, but that affects us much faster than piracy.
Please enlighten us.
