Mermaid Haus Jewelry review for Pinterest

There is a bug or something wrong with this app. I have been trying to connect my shop with pinterest. However it is a continuous cycle of going to connecting the page to logging in, back to connecting. It NEVER connects. I cleared cache & cookies, tried a different browser, restarted my browser, uninstalled/reinstalled the app. Nothing works. Shopify tried their best to help, however this is on pinterests end. I contacted pinterest however, they basically told me to do everything I already did. I guess I will just uninstall this app and not sell on pinterest.
