Proa review for SC Back in Stock Notify Me

Not working good and support takes too long. I have been using the app for days but its not 100%. Also e-mails notification delay to be delivery to costumers when I restock the item. I have been trying get it solved with support but they keep saying devs are working on my issue. It has been more than 20 days now, my free trial period its over and I am already being charged and the app it's not working good. Not a good experience.
