How do I read, or continue to read, eBooks and texts on other devices (synchronization)? You can use your user account to log in on up to five devices. You can also synchronize the reading status between your registered devices. The tolino eReader handles this automatically for you when you close the eBook on the tolino eReader after reading. Please note that both devices must be connected to the Internet for automatic synchronization to take place. You can also initiate synchronization manually at any time by tapping the circular arrow symbol in the right corner in the “My books” view. You will need to make sure your device has an active Internet connection for this as well.
