How do I re-install it?  I’m not much of an app person if at all.  Do I have to delete the current one first, or can I just install over it or something?

I’m in Portfolios. on on the website using my iPad.  I see all of the stocks with prices and daily change.  Recently, the up and down numbers are in color blocks. Just before that a couple of days also, I only got the changes but no stock price.  I’s the analysis of the portfolio stocks that find so helpful.  I used to be able to hit stock and get all of analysis and news articles for the previous year or so.  This stopped on June 5, all of the articles were there before June 5th.  Did I exceed my memory space on iPad due or other mail attachments?  I deleted the email, and the analysis and news stories did not come back for June 5 and more recently.  Then when I got the colored boxes of price changes, all of the storied s went away.
