Greetings D3P Customer, Thank you for contacting D3P Customer Support. Marvel Puzzle Quest does not sync in real time between devices. What this means is if you participate in an event, progress through chapters, or chat with your Alliance, it does not update to your other device. This can distort tournament rank and rewards, as well as prevent you from viewing alliance Chat. We recommend sticking with one device during gameplay as to not risk loosing points and ranking, as well as being able to view your alliance chat. If you have any further questions or concerns, please feel free to contact us again. Best Regards, D3Publisher Customer Support Team
