Why? For what? Hows? I dont get it?

This WAS the best app ever. But now it crashing and keep saying follow failed check your internet connection theres nothing wrong with my connection. Its been doing this for like a week now. Anything I do involving IG no longer works even with other apps. Its not letting follow people at all. Not even on IG. Idk if its the new IG update or this app. Some fixing needs to be done like now

Nickname for what?? about 5000 Followers Free - Follower Likes for Instagram, v1.0.4
