Instagram not showing posts I am tagged in.

Hello,

So I was invited as a collaborator on a post, and I accepted the collaboration. A few hours later, the post disappeared. The post wasn’t taken down by the original author or Instagram, nor was it archived, and it still shows on my post count that it’s still up, however it is not. And when I was just simply tagged on a post by the same person, I was initially able to see the post, but then the post disappeared on my end, however when I switch accounts I can still see the post that I was tagged in. How can I fix this?
