Gems do not transfer cross-platform. I.e. if you swap from an Android to an iPhone, or an iPhone to a PC etc., the gems will stay on the first device. Additionally, any gems you get on the second device won't carry over to the first device either (obviously.)  I think from what you said you switched from a phone to PC, so that's the problem. My advice would be to choose one device to accumulate all of your gems on and only accept gems on that system to get the most out of it. Hope this helps!
