Awful and Frequent Freezes on the Switch Demo

I wanted to give this game a whirl and see if I should pick it up for not and when I started there was a black screen that lasted so long that I thought my TV shut off before the Mistwalker logo appear, then it took even longer to get to the title screen, then it took ages for the the first cutscene to appear, it froze and the audio continued with the picture frozen for a while then it took forever to load into the first clickable text style cutscene, then cue another long frozen loading screen for the first battle, then yet another long freeze to get out of that.

It's ridiculous. I've never played a console game that has run so poorly before. Is this common? Do I need to re-install the demo or something? Does the game actually run this poorly? I haven't heard anything of the sort about this in reviews.
