thanks Oleksandr for your prompt attention to this.  I tried as you suggested and deleted and re-installed the ap.  I also power cycled my iPad.  All to no avail, the same thing is happening, which is that the ap closes when I access an analysis or transcript.  It does not happen when I access a news item.  My iPad is 10.3.3 and claims to be up to date.

No problems on my iPhone, BTW.
