Bundle Builder: Custom Bundles

I was so excited to finally offer build a gift box feature however this app does not work properly. The backend will often not show up, often show an error message. Most often, the backend shows "create your first builder!" screen even though I already have a builder live on my website. This is problematic because it takes forever to reload and reload and reload and try to get the builder that is LIVE to even show up on the backend in order to edit it. As of today, the live version is showing only 4 steps, but the backend (when it decides to even show the builder) shows 6 steps. There is no live chat, so I feel like there is no support regarding this. What it boils down to is that this is the app that many of us need/want, but for $20/month it is insanely expensive for an app that doesn't work properly. If there was a free or even cheaper version, you might be able to stomach these issues despite the subscription fee. But for $20/month, almost the same price as the entire Shopify subscription, I expect the app to appear in the backend, and not have discrepancies between what is LIVE on the website and what the backend shows. I would love to revisit this app eventually in the future but as of now, unfortunately $20/month is way too much for something that presents incomplete steps to my customers. I can deal with the backend not showing up and being annoying, although it shouldn't,- but now that it is showing LIVE only 4 steps to my customers, who now can't complete their gift boxes, while the backend shows 6 (when it decides to appear) there isn't even anything I can do about this and it makes my shop appear incomplete, glitchy, and therefore unprofessional.
