Mst: Preorder + Back in stock Delisted

This app is presently not opening i have asked for support but no answers as yet

Worked great for a few years, doesn't work anymore. I have contacted support and the only thing they say is they are working on it but it's been weeks. I can't even pull it up in Shopify admin.

Have created multiple tickets and no response in the last month. 504 error cannot bulk update stock.

This app doesn’t work, we had our developer check the code and every tune was working correctly it just didn’t didnt items that were out of stock. Twice I emailed support and they didn’t reply. Shocking customer service

I emailed the developers about installing this app to try it for the 14 day trial, but never heard a word from them. The only way I knew it was installed was that I noticed the extra charge on my Shopify account. I had asked a few customization question that were never answered. When I checked on the installation, I noticed that it wan't working and emailed the developers immediately to see if they would uninstall the app. It's been several days with no word and an app on my site that doesn't work. I was really hoping this would be a simple way to collect customer data on out of stock items, but it's just turned into a clunky broken add-on. Super disappointed in the lack of communication.

I initially liked the app, however the functionality on the back end for me was not working properly and that's where I got lack of service. App was installed and I needed some help as it wasn't functioning in the restock date area. I sent a message for help on this and no reply back. So I uninstalled the app and it's still remains. Why is it still there?
