Streaming for iPhone App Reviews

This version is not working. How can Apple let this version out and force everybody to update. This is not a game. This is use for trading stock. It always stop working when you want to buy or sell stock, stupid app. I use iPhone 5S, this version is really bad how dare Apple let this happen, also I cannot go back to use the old version, I feel so stuck for the first time.

Invalid error code prompted upon trying to log in. Doesnt work. (Iphone 6, ios 8)
