I had it for a month or two but lost it a week ago. 🙁
Loss of functionality strangely coincided with switching to playing through my King account. Just a heads-up to people in case they play on more than 1 account on the same device.
I agree...Same thing happened to me. I was playing with 2 devices simultaneously those days, and it ked to lose the feature. And I got it after more than a year.
