I am getting conflicting answers. Can I still use GCM and Simon VGC to meet min spend on Amex Biz Plat and Amex Hilton Biz? In the first half of 2017, before I took a hiatus, I was able to successfully do it by mixing it up with organic spend and never buy more than 2.5k/day (5k/month) of GC at a time.
