In all the Pokemon games (I think), there is an "Obedience Cap" of sorts, which gets increased as you beat Gym Leaders/Island Kahunas. But before beating any significant figures, there is still a Cap; I think in Ruby/Sapphire, it was lvl 20. However, I can find no information ANYWHERE about what the original Cap is in Sun/Moon.
Any ideas? ¯_(ツ)_/¯
