You have to play it safe... when you switch from one device to the other, if it's been more than 12 hours (maybe even every time!), you should put the second device into airplane mode before you launch RR3, then CLEAR LOCAL SAVE! Then go back online and login to your RR3 game account. RR3 will detect your save and ask if you want to restore. This way you shouldn't lose any progress/rewards.
