Purchase products for extra gems ???

Same, I tried it. Looked rewarding and then got cheated out the gems after doing exactly what it said. Its a very broken system. The worst part is the tracking was working, it was seeing my milestones in pvz2 for the other game. But it didn’t “credit” the ad to me despite it being the first time I ever saw it. Think the whole process is just broken going in and out of apps. Was highly disappointed and I don’t take anything seriously that it advertises anymore via that system.
