I've noticed something similar, but with comments. When you hover over the post, it shows, for example, 1,200 likes and 54 comments. Yet, when you go to see the comments, there are only 51.
If I check from a private session, not login into Instagram with any account, I can see all 54 comments. If I login with any account, I can only see 51 comments. Even login in with the account of the post, I can only see 51 comments, but IG stats says there are 54 comments.
