I had a weird glitch happen last night while redeeming against a travel purchase on the app.
The redemption took at extra 10% of the billed points, left me with negative points before the 10% travel points rebate. The net showed points left just as if I hadn’t received travel points at all. So for a moment, I thought maybe my account had lost that rebate.
Oddly though, the redemption confirmation email showed the corrected / expected point total remaining, including the rebate. And today, the web site also shows the correct total.
So if you see youself shorted on points after a redemption via the app, don’t panic.
