I think you’re failing to understand how companies tend to work. The front end teams and backend teams are usually different and want to work on different things. But for the front end team to build an app with the data they need, they need the backend team to change the rest api to provide different data. That kind of change is usually not very interesting for backend teams to do and they stall, while the frontend team is waiting By the seat of their pants for days for a change which they feel should be pretty damn small. One easy way to fix this is by using graphql instead of REST. Now the frontend teams have access to somehow get the data they need and are thus unblocked.
