Hope that helps You're not using your createStore method, rather importing it from redux again. So the middleware is not added.
code :
import React, { Component } from "react";
import { Provider } from "react-redux";
import { createStore } from "redux"; <--
import reducer from "./src/reducers";

export default class App extends Component {
  constructor(props) {
    this.store = createStore(reducer);

  render() {
    return (
      <Provider store={this.store}>
        //...My App

Actions must be plain objects. Use custom middleware for async actions, but I am using redux-thunk

fixed the issue. Will look into that further I'm not sure if this is the root of your problem or not, but when you're using mapDispatchToProps with the connect method of react-redux, you shouldn't have any reason to also use bindActionCreators. It should work fine to have the following:
code :
const mapDispatchToProps = (dispatch) => {
  return {
    pushVideo: (video) => dispatch(pushVideo(video))

this one helps. It's not the correct way to configure middlewares with redux devtools, according to redux devtools' readme, you should do this:
code :
// don't forget import { compose } from 'redux'
const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const store = createStore(reducer, composeEnhancers(middleware));

will be helpful for those in need In case anyone comes across the same issue. The problem was not in the code shown above, or how I was dispatching actions. I had a duplicate definition of the redux-store in a different file, which overwrote the definition with the middleware.

seems to work fine Actions must be plain objects. Use custom middleware for async actions. , Your store setup logic is wrong. You've got this:
code :
import {configureStore} from "redux-starter-kit";
import rootReducer from "./reducers";

const store = configureStore({
    reducer : rootReducer,

Redux/thunk Error: Actions must be plain objects. Use custom middleware for async actions

will help you You fetchPosts action returns a function, whereas it was expected to return a plain object.
Returning a function is required for async operations in redux. But you need to wire up a middleware called redux-thunk.
code :
import { createStore, applyMiddleware, compose } from 'redux'
import thunk from 'redux-thunk'

import rootReducer from './reducers'

const store = createStore(
  reducers, // your reducers
