iPad screen rendering too big

In the past few days the rendering of the home page no longer fits on my IPad.  The same is true of the individual stock summary pages.  However, the sub-topic pages, like “key data”, still render correctly.

For several weeks prior, the same problem occurred, but it was possible to manually re-size the screen.  That capability seems to have gone away.

The specific symptom is that the left margin is incorrect - the left most inch or so of the screen is not displayed.
