Yesterday and today I was successful syncing my Touch to last page read from the Android app. To my surprise, highlights and notes carried over also!
I don't know how long a period of time must pass for it to pull off the latest read stuff, but I know it doesn't happen immediately. I just tried it again with the intention of waiting 10 minutes. I got sidetracked and didn't check until 1/2 hour later. I'll have to try and pin it down some more.
I wish B&N would acknowledge the sync issue and their quest to fix it. Why can't they just post a sticky on the BN.com tech support forum?
Now, the only thing left for me to rant about is the homescreen. By the way, it's day 16, and I still have those same four recommended books from day one. OK, I'm done.
