I am having trouble with downloading in any assets from the sketchfab library into my twinmotion model. I am already signed in but it continues to ask "please sign into download". I have tried to log out of all browsers and all things signed into Epic Games but this does not work. I have also tried uninstalling and reinstalling Twinmotion but again to no avail. I don't understand as the Quixel Megascans works fine and I can download fine from there.
