The idea of "Scrum" in my mind is likely very different from the one you are familiar with. In the official Scrum Guide we find Scrum's definition: "It's hard to criticize Scrum" because the definition is so vague.

In addition to all of their development work, the engineers are now interrupted frequently by the scrum master who is asking when the "Java code" for the React app will be done.
