Why is it better to use the default unfollow mode instead of unfollow scheduling?

We recommend using the Default Unfollowing method instead of Unfollow Scheduling.
That’s because unfollow scheduling is more likely to be noticed by Instagram as an automated activity as it has a consistent pattern.
This means Instagram could then flag your account and place limits on your follow and unfollow actions.

Additionally, as unfollowing is a server intensive process, by using unfollow scheduling, you are running the unfollow process for a fixed period on a daily basis. This will dramatically decrease the speed of other interactions (Likes, Comments, Story views) and will affect your promotions. 

If you would still like to use it, make sure to adjust the start and end time ranges to shorter periods (E.g. 3 hours).
