Instagram login problem

I’ve activated social login. My instagram client has been reviewed and approved. But if I try to login with instagram, I authorize it by filling all my login info and the page is redirecting to my homepage as logged out user. After I click instagram icon second time, then it allows to login successfully. My client is setup with the info you’ve provided on your guideline. My homepage and Valid redirect URI are the same. So I don’t know what causes this problem.

Thanks.
