Smart Product Filter & Search

This App works and suddenly it will be down and you will not see any filters. I am using this App from past 6 months and I have faced issue multiple times. Today the App is down and i am not able to see all the products in the website and it effected my sales. I am not sure if there is any maintenance activity or the developer doesn't care to inform about it. I request everyone to stay away from this app. Not worth having it. Make sure to select an App which has 24/7 support, a working phone number maybe and notify customers properly when App is going thru maintenance activities etc.

I am updating my review based on your reply here. If you have upgraded your App from Version 4 to 5, did you inform all your customers about the upgrade so the stores can check proactively to see if there are any issues and report them to you immediately. So you guys are upgrading an App and not testing if the App is backward compatible. Remember stores are paying for your App and this is not a free service.
