Yes, it does have glitches. But, we absolutely loved the app and the fact that we could order 5 or 6 drinks (beer) at a time and have them delivered to our room. We love to watch sailaway from our room while getting ready for supper. Once I ordered, and I didn’t think it went thru so I ordered again. 20 minutes later both orders arrived at our room. No charges to our onboard account, but we did give the bar steward a good tip. They will get the glitches worked out.
On Celebrity we could only get 1 drink at a time and if my husband forgot my cruise card them he was charged for the second one and we had to go to bar to get them.
