I'm playing two cities in a private region. One is doing well. The other, well, not so much...
In an attempt to restore some balance, I decided to send 30k to the less fortunate city via the region-based "gift" feature. The money left my good city almost immediately, but hasn't yet (1hr30 real time) arrived. I've tried leaving the game and opening it again, but all I seemed to be able to trigger was a "Your gift has been sent" notification.
How long do gifts take to arrive? Is there a secret trick for speeding up the process?
