It's not nonsense. It increases your chances to hit, but not guaranteed.
I had $2.3k spent and hit on everything from yeezys, big bangs, to bred toes. My timer reset 2 weeks ago and im at $65 spent. Got on WL this time for Game royals, luckly it changed to a W.
This happened to me, the store just told me to close out app and reopen it. The store had really bad reception and they said the voucher didn’t load completely the first time.
