Session flash messages are not working in Laravel 7

Question

Since I updated my Laravel version to 7.4, the session flash messages stopped working in Views.

Here is what a part of my code looks like: Web.php

Route::middleware(['web'])->group(function () {

 Route::middleware(['permission:super_user'])->group(function () {

  Route::get('/get/{id}', 'TestController@show');
  Route::post('/set/{id}', 'TestController@update');

 });

});

Controller Methods:

public function update(Request $request, $id){

    $message = new stdClass();
    $message->type = 'success';
    $message->text = "Updated successfully!" ;
    session()->flash('message', $message);
    return Redirect::back();

}

public function show(Request $request, $id){

   return view('pages.account')

}

Session data is there but flash messages are getting lost somewhere between redirection, not sure where exactly. I tried several solutions like session reflash, removing the web from middleware but it didn't work. Any leads?

Edit: I found out that session flash exist in this method. Which means app redirect erasing it?

function back($status = 302, $headers = [], $fallback = false)
{
    dd(session());
    return app('redirect')->back($status, $headers, $fallback);
}

Try this solution. In controller method:

public function update(Request $request, $id){

    $message = new stdClass();
    return redirect()->back()->with('success', 'Updated successfully!');
}

In blade file do this:

@if(session()->has('success'))
    <div class="alert alert-success text-center">
         {{ session()->get('success') }}
    </div>
@endif
