So with bountiful harvest and season, army sizes can exceed 24k provisions. However mobile presets only allow 24k provisions of each unit to be set. This is a problem when trying to set a nuke preset with 26k axes.
I am looking into this issue
In the meantime, if you have a co op that uses the browser or Android app, you can have them save your preset as you want it. Both have the options to go higher than the 24k
