Problems with VTube studio Iphone app

Guys I'm new and I beg for your help! So I have a model which looks completely fine in PC VTube STudio version with autosetup however on Iphone VTube STudio with autosetup it shrinks (both are the latest versions). I need to make it work specifically on Iphone's app, what should I do? I don't understand what's the mistake there.
