Pokemon United clothes not loading

Hi! I've recently got Pokemon United, it's a fun game but all the clothing in the store do not show up on my character model & even after I purchase them they also won't appear, instead a "downloading data" dialog.

I've already uninstalled & reinstalled, but if it's going to be like this it really discourages me from ever using real transactions for clothing that won't appear.

Is there a way to fix this?
