It seems some of the default settings in Chrome were causing problems, it's been fixed and everything should be nice and smooth now.
P.S. Page is intended to be very Mobile friendly as well. Layout has been build around mobile first, so no scrolling until the cows come home, just open the page and click...
Edit. Mea culpa, as I was fixing the issue with the setting I missed adjusting the reward setting as well. It's all taken care of now and hopefully I caught it before anyone accidentally got a lower reward than intended. I was raising the reward, so it was a facepalm moment noticing it accidentally went the wrong way. Anyway, all fixed now...
