Copilot and large documents

I have figured out a way to move forward.  I had to go back to the regular copilot App.  I stored my content in pages.  I will probably end up with about 40 pages.  I have found out I can have Copilot refer to a prior page.  That helps with Sequence and helps to keep some of the context for Copilot.  Just a heads up to anyone using the copilot app.  I encountered a bug in copilot.  Probably a fluke.  But while processing one of Copilots responses only got half way done.  It came back with half a page highlighted.  I tried reopening Copilot and rebooting.  Still highlighted.   Issued a new conversation to clear it.  But I lost half of my page content.  Good thing I was pasting into Word all along, so I was able to recover.  But it could have been bad if I did not have things backed up.
