Stocks App - One stock stopped updating

I am hoping that Apple would contact Yahoo Finance and ask them to fix this information feed or that Apple would consider negotiating with the stock exchanges to get information directly from them instead of a 3rd party. Apple has much more weight and pull than I do as an individual. After all, you are a multi-billion dollar company who decided to do business with Yahoo Finance when you designed and developed your Stocks App and decided to import information from that source. If Apple would ask Yahoo Finance to fix their stock feed, I would really appreciate it or if Apple would change your Stocks App to import financial information directly from the NYSE, NASDAQ and other stock and bond exchanges around the world, I would appreciate that as well. I do not have a Yahoo id and do not plan to get one to report this problem because I have no need to do business with them. Frankly, I am surprised that they are even still around. Much like the rest of the DOT COM companies from the 1990s and AOL they have just about come and gone and been replaced by Google, Facebook and the other social media companies. If Apple does not want to provide more customer support for this issue, then so be it. I am optimistic and hopeful that your company will use the weight of your power to get this fixed. Little guys like me do not stand a chance with obscure companies I do not do business with directly. I hope you understand. Merry Christmas and Happy New Year!!!
