I too miss this Option! And it lasts very long to get an answer here…..
On my kindle I found out when you click the buy button for getting slings and coins there is on the right side a button: get free power ups! Then you can watch a video and get power ups but you can not get a specific one….
And it is not available on my smartphone!

I got an answer: on older kindles (2012!) It’s no longer running after they made an update…..It would have been nice to be informed about that so I would not have installed the update….

Anybody out there who can help? I think I am not the only one with this problem? Send even emails to Angry Birds, but no reactions!!!! What had happened? I am waiting for an answer so that the play can go on!

Same thing to me since this morning!!!! It’s not funny….
