MaxPass and Jedi Training

I am reading that JediTraining requires early morning registration. Can that be done via smartphone if one gets the MaxPass? Thanks

Jedi Training: Trials of the Temple is a show that does not have MaxPass availability. You can watch any of the shows during their times, but in order to participate in the show itself requires registration. Registration opens when the park opens, and is typically a popular one. So, if you want to participate at a particular time, the best bet is to get in line at the registration as early as possible. All members that wish to participate must be present, as participants are asked a few questions. Unfortunately, you cannot register via phone.

Thanks. I was hoping that I can let my grandson sleep later and I can register him during MagicMorning. Too bad it doesn’t work. getting up early is hard even for Disney fun.
