On Bakery Story, I will always get the option to watch 10 ads for 10 gems. This offer pops up after 24 hours.

But whilst loading Restaurant Story, I see the option of earning free gems to the top right side of the screen. But then when the game loads, the option is gone. Even if I didn't get the free gems on Bakery Story, the option does not appear on Restaurant Story, so I'm wondering if this is a bug...

The free gem offer loads on my iPad, but on my S5 there are no free gem offers for either games.

Is there some way to trigger the free gems offer in Restaurant Story?
