I am very much disappointed by the fact that amazon removed its support for windows mobile after15th august.I used to order a lot from amazon app now its not happening.i am using windows 10 mobile on my Lumia 640.At one side when windows 10 arrived for mobile different companies are making beautiful app for their windows phone users amazon decided to remove its support which was very disheartening.I think they should do something about it because they are loosing a big customer base of windows mobile user where other e-commerce apps are excelling.
