MGP25 checkpoint class
https://github.com/muthu-kc/instagram-checkpoint-and-rate-limit
This is a liam cottle library with instagram private api checkpoint issue solved.
Clone repo and run example folder on your browser. you can see how it's works.
Do not use this checkpoint feature for bulk like. There's a chance that you will get checkpoint again or you might need to verify profile once you reach limit.
I created this solution for my own project. I post here for others to use it. Code is not clear and not meet code standard, so i didn't commit the changes to original library.
Happy coding!
