Amanda Lapalme Art review for Amplify | Bundles & Upsell

Caused an issue with my theme and I had to uninstall everything and get a new theme. Got everything set up and went to reinstall this app, because I actually liked it despite the theme issue, and am met with {"detail":"No user matching this token was found."} and can no longer install it on my store at all. Wasted an entire night redoing my entire website just for this app and am met with this. Incredibly frustrating all around.
