Thanks for your comment AndyKrumrai
The tip we gave in this article is a workaround. It wasn't an intentional feature Quickbase designed, but it is something that works because of the way that sandboxes were developed. I understand that not showing sandbox apps in My apps adds friction, especially for your use case.
Unfortunately, our product team does not plan to significantly change the current sandbox feature. While we continue to support and maintain it, we're focusing our resources on developing Solutions APIs that lay the foundation for future no-code application lifecycle management (ALM) capabilities. You can work with your account team to learn more about how all builders, regardless of their technical skills, can start using Solution APIs.
