The chanting takes immediate effect when there’s no offense or when there’s very little offense, but with offense, the action is delayed. So, offense means to offend a pure devotee, to disobey the guru, to offend the scriptures, to put material conceptions on the chanting, to be inattentive while chanting and especially to chant so that one can do more sinful activities. If one thinks that, “Well by chanting I get purified from sin, and then later I can do more sin.” all these type of mentalities are called aparadha or offense. So especially the offense to the pure devotee completely pulls out one’s devotional asset.
