Reliability of P2P synchronization heavily depends on being able to deliver all message to all devices in the group, because each device has to hold the state of the entire network and constantly update it. If a device misses a message, it will have an inconsistent state and will not be able to recover from it. This change improves the reliability of the P2P synchronization by adding a mechanism that ensures that all messages are delivered to all devices in the group.
