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

The button did nothing on the customer side ...

Send a message for assistance and have not received a reply. Will show up as send alert to messenger but instructs customer to check a check box that does not exist. Would have loved it if there was any support from developers.
