My favorite - schedule the same table, same time for dinner every night of the cruise. Occasionally it comes up with a time, but no options so I tell it to make the reservation. After a long delay it returns the message can’t make that reservation because it’s not available 1 or more nights. Then why did it show it in the first place?
I finally gave up on the app for everything. For as long as this app has been in use it shouldn’t have as many problems as I see posted.
