I booked a stay 190k point stay using app but was short 30k points. A few days later I made up the difference by buying some points during a promotion. Checked the app and nothing regarding any amount owed or if points required being changed. Fast forward two months (a week before trip). Checked my reservation on the desktop website and said it that I owed 32k points still. Customer service agent was the worst I've ever dealt with. He was slow and literally unresponsive (think Zootopia Sloth) and was not able to do anything to help me. I had to purchase $400 in points to make sure I had a place to stay during my trip. Long story short, if you are going to book a trip on points or using FNC, use the desktop website, the Marriott app is useless and doesn't show you all the details of your stay regarding points and price. If you didn't pay for your stay upfront I would recommend you use the desktop website, otherwise you might get bonvoyed like me. This makes me really consider switching to Hilton or Hyatt next time I travel.
