I have zero issues with new technology, quite the opposite in fact.I wouldn't blame you if you didn't, but I wish you would give mobile ordering another try. The only thing I hate worse than learning new technology is standing in line, so I tried mobile ordering as soon as it was introduced and it's worked so well for us! Also, the system has greatly reduced the number of people tying up tables while a family member is standing in line waiting to order.
The problem we had is the app simply would not work with our account. We tried it from 3 different phones all with the same result. We would get to the point where we would pay and it would give us that oh so helpful "Opps! Something went wrong!" message.
Both Guest services and Disney IT were unable to fix the issue on day one. They chalked it up to the system being overloaded. (We were in MK on 10/1/2021) We were only there for 2 days on our last trip so we just dealt with it as I was not going to waste the limited time I had standing at the Guest Services desk on day 2 hoping someone could figure out what was wrong.
The app worked for nearly everything else. I could unlock my doors with it, get attraction wait times, make TS reservations, but mobile ordering was a no-go. The door thing was nice as the resort was also unable to get the Magic Bands we just ordered to pair with our account.
