I want to change the UI of ios and android apps without release.
For example, show/hide images, display position, etc.
We thought about distributing these parameters through the backend API that the native app refers to, but since this API is designed as a resource server, it is unnatural to handle parameters that are closely related to the UI, which we want to avoid.
Firebase Remote Config is a better option, but its major disadvantages are that it is difficult to handle data with complex structure, and it is difficult to operate via API.
Is there a better alternative to Firebase Remote Config as a data store suitable for managing parameters closely related to the UI ?
