I don't know why. Since update, i can't check out anymore. The shipping option isnt available to any item in my cart even from china. Before this, have no problem with address. Im not living in slums, i live in city. How can shipping can't reach me!?? Then i chat with the agent, i already change the address, check the app is latest version or not, i even chat with the seller, and he doesn't even know what's going on. Every item cannot check out. I mean everythinggg
