Back In Stock via Messenger

Nov 2020: This use to work great... now had to disable since wasn't working and support didn't say any fix... now their app keeps stuck in a redirect loop when clicked... so unsure of the current problem but will check back in a few months to see if they get this fixed, but disabled for now since would show an error on the website and couldn't have that. Hope they can fix

Sept 2021 update... still not working... error on installed app of missing page, their app page from shopify when try to reinstall gives an error as well... so been paying for a year for a dead app.
