If you've been playing Founders version only, it might be a good idea to switch to basic RS.

This is embarrassing, but I just today realized why I couldn't watch an ad to speed cooking on my tablet but could on my phone. I had different versions installed! Fortunately, the phone is where I played my secondary accounts, which get ads-for-gems offers, so I wasn't missing out on gems, just a couple of speed-ups. Still, not my finest moment--I wouldn't even have noticed if I hadn't deleted and reinstalled on my phone and accidentally grabbed Founders instead of the basic I'd been using.

So anyway, it's possible your account has offers you haven't seen if you stayed with the last version released.
