Question about Le Creuset Signature

I always grease the pan well before use and leave the meat, for example, for a relatively long time until it comes off by itself, then I turn it once. that works well. I also wash the pan only by hand with water and without soap, so that the patina can form after a while, which helps a lot that other foods don't stick so much. Meat, spaetzli and vegetables all go well, but hash browns stick anyway.
