To run:

Replace localhost with your IP in native-app/relay.js

yarn/npm install (in both /server and /native-app)

yarn/npm run start (in /server)
expo start (in /native-app)

IMPORTANT: The issue can be simulated on the second run of the app since cached query data is needed.

Observed behavior:

The first refetch request is executed but the component does not rerender nor the callback is called. The second refetch works as expected.

Note: There is a warning that viewer should not be undefined but I believe it is not related to the issue at hand.

// native-app/App.js
  componentDidMount() {
    console.log("componentDidMount");

    this.props.relay.refetch(
      { filterBy: "beta" },
      null,
      () => console.log("Refetch Done (without delay)"),
      { force: true }
    );

    setTimeout(
      () =>
        this.props.relay.refetch(
          { filterBy: "beta" },
          null,
          () => console.log("Refetch Done (with delay)"),
          { force: true }
        ),
      1500
    );
  }
