CPB ‑ Custom Product Builder

I would really like this App to work, unfortunately bugs keep showing up. Unexpected glitches suddenly appear: pages with errors, items show up as out of stock when customers try to add to shopping cart, etc.
The developers are quick to respond that they are looking into the issue but over a week has passed and no solution. We are losing sales.... even though the developer keeps charging their $50 USD monthly as if the app worked.

The issues mostly arise as the developers keep upgrading the app without properly proofing it before releasing the upgrades.

The app works great, when it doesn't come up with glitches. We sell custom bags and our clients can mix and match all the components and see their finished product on screen. One thing that the app does not do -- unfortunately -- is syncing with Shopify's inventory for the components. Your clients could purchase custom items which you might not be able to supply as they are out of stock. At $50 a month it is one of the most expensive apps, inventory syncing should be included.

Support is atrocious. Lots of bugs and things that don't work correctly. When trying to get aide or help, it takes DAYS before a response, which is wayyyy too long when your whole store runs on their app. When you do get help, you get moved from person to person. Have had an issue persistent for weeks, and it still isn't resolved. I installed and setup from top to bottom another app by the time I've even gotten a simple response. Goodbye and good riddance CPB

I uesd the app for 4 days, didn't work like it should. Waited on support to fix the problem, just kept getting passed around, but yet they say there is 24/7 support.
