Problem of number of IG page removed the subpages linkage from IG

Instagram Marketing
1

just found 9gag and quite a number of IG pages all removed most of their subpages linkage from their IG profile, is it because of some recent policy change by IG?

I did not hear about any changes regarding the matter, what could possibly be? because they still have a page link there

What was the content of those 9gag?

I did not notice this until I read your post. Not sure as well though if they just revamped their profile or maybe they just gave way for the links on their giveaways to be on the bio

Here are some samples
