Looks like Digimon Universe: AppliMonsters is going to be making a move.
Appmon will be moving to a new, improved timeslot, at 9:30am on Saturday, beginning April 1st.
Appmon's move means that it's prior timeslot will be filled by that lovable scamp Boruto, in reruns of his upcoming new series.
The move lines up with prior information we had of various changes coming to Appmon as story arcs swap over, and the 'new' elements should happen concurrent with the timeslot change.
At this time we have no information on if the show will gain a subtitle or change to a new opening theme.
Thanks to Mendinso and shin for some information used here.
Update- Updated the above information now that we know it's new timeslot.
