I've completed 3 polls and have received no gems, i always get a screen to pop up saying "you have already received your reward for today" and my gems don't increase.
As well, my gems are disappearing. I haven't spent a gem since I was at 10 gems and currently I only have 1 available. I am not sure what is going on.
