Q1. What does "checkpoint_required" & "challenge_required" error mean?
If you get checkpoint_required, it means that Instagram wants you to prove that you are the owner of the account. It can easily get triggered if you login in a country that you don't normally log in from, or you log in from a new device.
Simply log in to your account via the official website or your mobile device - that should fix it. If you still get the error again, it means Instagram dislikes your device's IP and that you must log in to your account via Instagram's website and your device's IP to prove to them that your device's IP is a human.
Sometimes, this can also come if you have enabled two-factor authentication on Instagram. Disable it and then try again. https://help.instagram.com/566810106808145
Q2. Loading Error? Receiving "Something went wrong" error message?
This sometimes can happen due to Instagram server errors. Follow these steps to resolve the issue:
Q3. Too many followers and following and loading taking too much time?
We don't support account with a very high number of followers. We have tested the app with 20,000 followers. Before purchasing anything, test it yourself.
Q4. Two-factor authentication error?
That means you have enabled the Two-Factor Authentication for Instagram login. You can temporarily disable it and then come back to login. This setting takes some time to reflect. So wait for 5 minutes before logging back in. https://help.instagram.com/566810106808145
Q5. What if I log in on Instagram through Facebook?
You can go to the Instagram website, set a password then come back to login.
