Late last night, I realized that all of the bookmarks that were synched from Chrome running on my computer werre now gone from the N10. They were brought over when I first set up the tablet into a Desktop Bookmarks folder. The regular Mobile bookmark folder has always remained empty. Google tech support walked me through the process to restore synch but my tablet would not keep the Synch Setting Button in the ON position. All of the choices of what to synch are greyed out. The tablet still recognizes Desktop Bookmarks as it is the first choice given me when I now bookmark a web page. But it no longer exists so my bookmarks go into the Mobile Bookmark folder. When I setup the tablett, it was with JB 4.1 and now it runs JB 4.2. I do not know if the upgrade disabled the synch function of the tablet. I have already processed an exchange under the 14 day return policy of Google Store. I'll probably now do a Factory Reset to see if things change. Anybody ever lose all of their bookmarks that were synched over? Can you still access the synch mode which is located in the tablet's Settings, by clicking on your sign-in email address. Shelly Of strange interest, my bookmark for this forum on my desktop computer also disappeared last night?
