After the latest update, the pre market price is incorrect. For example, I have checked NASDAQ for Apple pre market price against the app. In the screenshot, you can also every other stocks is the same pre market price as of -0.01% or -0.00%.
Also before the opening market, all the actual stock prices reset back to 0.00%, when the market opens then the market price will update. This never ever occur in the previous version which is good.
Happening in both iPhone 6 Plus and iPad Air 2.
