Fix the mobile app - either it or the real-time feed is broken (or both). Data is wrong!
For at least a couple of weeks, the mobile app, which I have on an Android phone (and just reinstalled, which didn't help), has incorrect stock prices. Also, the price and little graph on each line appear to be from a previous day (one or two days earlier) BUT not necessarily the same day. So, the price may have fallen but the graph shows a green graph with the price going up - and vice versa..

If it's not fixed, I'll have to either log into my broker feed, which is a hassle or track my watchlists on another app. I like Yahoo's format and, until the data became erroneous, it has been my go-to place for watchlists.
Note that the website has no such errors.
