This is a known issue and one that was highlighted recently about collecting rewards. You need to run at least one WTTT run on the device you want to collect the reward on or the game doesn't register that you have run WTTT since the last reward.

If you still have the old device and haven't collected the reward on it then you can do the following:
 * Cloud save on new device
 * Open game on old device and press Later at the reward popup
 * Cloud restore on old device
 * Collect reward
 * Cloud save on old device
 * Cloud restore on new device.

If you don't have the old device or have collected the reward and made progress on the new device then I'm afraid you've lost the reward for this week.
