I guess in the middle of November, Instagram started a review process and puts all new apps into sandbox mode. If you want to get out of it you have to submit a request which requires you to give them the use case and a video. I did so and I was declined stating that it was an invalid use case and Instagram doesn't allow it.
So is Instagram off the table or did I possible do it wrong?
I am having the same issue but the problem is that Instagram declined me using the IG login button stating that it is not a valid use case.
They started this review process in November so now I am wondering is that now even possible?
