Free bushes are no longer available to give someone?

Really? You should still be getting 1 green bush to give free every day. The other 2 green bushes cost coins to give as always. The timer for getting a fresh set of bushes starts 22 hours from the time you gave a bush from the last set.

Maybe a glitch affecting the timer? If it does not resume as expected, contact customer support through the "help" button in the game settings (green gear icon) and provide your user ID.
