I had the same thing happen! It was a “double” offer worth 1,000+. Customer service has not responded to my last few emails so I suppose they won’t do anything about it. It is frustrating because it took several weeks to earn.
Does anyone else still have this problem? I have the iOS version 1.21.5 and am still not getting double coins for VIPs. I'm wondering if I have an isolated problem or if this is universal?
