Session flash in redirect is not working

I have this code in my controller

public function deleteDependent(Request $request)
{
HMO::deleteDependent($request); 

if(session()->has('hmo_id'))
{
    session()->flash('status', 'Task was successful!');
    return redirect()->route('edit-user', request('hmo_id'));  
}
else
{
    return redirect()->route('edit', request('hmo_id'));  
}                                                                                                                            

}

And also this is my code in view

        <div class="col-lg-6 col-lg-offset-1">

            @if(session()->has('success'))
            <div class="alert alert-success">
             <strong>Success!</strong>  your request is waiting for Admin approval.
            </div>
            @endif
        </div>

Redirect is working properly but the session flash is not read by the view, what am I missing ?
