United MileagePlus X Customer Insights

1. Plus it was also a great tool to use some of your miles to purchase gift cards for everyday items as well... But then suddenly just quit working, it wouldn't let me log in, and it kept telling me it didn't recognize my account.

2. Nothing really makes a difference, on occasion you might get lucky and be able to buy a gift cardCan't even use it since the update, getting error msgs every time I try to buy a card.

3. 99% of the time when trying to purchase a gift card it says Purchase Failed and to contact customer support through email.

4. Once I did that, I was able to make gift card purchases again as normal! --------- This was a great app but now is full of errors, authorizes and puts holds on cars but never actually generates the gift card.

5. I also drop a star because they make it very difficult to delete a credit card once added (adding is easy), & the fact that you have to do this on your MileagePlus profile isn't even mentioned in the MileagePlus X FAQ.Update: United contacted me and gave me a potential solution.

6. I had large purchases I was looking forward to making with the app and my double points credit cards but the app will not complete the purchases of the gift cards I need to buy.

7. I have been using this app for at least 3 years at this point.The app was working great for a long time and was really helping me bump-up my miles.

8. Way to go in making it LESS user-friendly and slower right at the busiest shopping time of the year! Will be using my other shopping rewards memberships until this improves.

9. Right now y it takes forever to even load the page to purchase a gift card, then denies the purchase.

10. They advised me to go into my Mileage Plus account (website) and re-enter my address / phone number for each credit card I had registered on the site.

11. Two hours messing with this and gave up.Previously I would have given it 4 stars, but they overhauled the app a while back & removed an important feature--the ability to refresh balances on purchased cards.
