Right, that was the step that I was missing.  It did re-sync.  This is really cool stuff!   Very well done.

Now when I click on the book to open it or share the book (back with myself) it plays the first 4 pages then pops up a dialog that says:  "The page you are trying to Jump to was not loaded.  Change the Interact Mode Context to include the destination page and try again."   What is the Interact Mode Context?
I do see the folder called Player.  Is there something I should do to that folder before reopening the app?  I reopened app but did not indicate it was syncing again.  I logged into InteractPlayer.com and did not see the app restored.  I clicked on the button "show deleted apps" then "undeleted" the app and it came back, but it is not the most recent version.
I am using Chrome.  I retried with the same hanging result trying to add a single contact.  I was able to use the bulk importer to add one contact successfully.
Thanks, Alin!  I that's gonna get me over the hump!
Possible fixes for this include providing a way to make the font in the Word Highlighting dialog smaller, make the dialog box bigger or add a scroll bar to the dialog.
I was able to complete the word highlighting "in the dark" by just memorizing the words that wrap off the bottom of the screen and just completing the taps as anticipated.  I had to do it a few times to get it right since there is no way to adjust the timing on a word by word basis for the words off the bottom of the screen.
Page Titled: Page 33 – Drag erase works fine in the Builder on the Mac, but there are black artifacts that appear when drag/erasing on the iPad.  May be related to the bug above.
This same crash happens on Page Titled - Page 27.  It is most likely related to the same bug.
Yes, I tested this on the latest Builder, Build 343.
So you are saying that invisible objects will now trigger an intersection or that, by design, invisible objects will be ignored?  It is so much easier to create objects in the app, then to have to create one or more invisible png file and import them into the Builder.
