Thank you for your feedback on v1.4 at this forum and on the App Store.
As some of you may have expected by now, the upcoming iPhone version will have the sync feature from day one. Therefore, we love to have as many users as possible to try out the current iPad version now on
sync.
You might say, "Sorry, I can't help. I only have one iPad."
Actually, you can help even if you have only one iPad.
Here's how. Open a book, go to some page A, and do "Upload Reading Progress". Then go to another page B, and do "Download Reading Progress". See if it takes you back to page A.
You can also do something else between the upload and download operations to make the test a bit more complicated if you want.

Your help would be greatly appreciated!
