Instagram forgot pasword and lost gmail and mobile number

Instagram highlights of someone is visible on their account but not loading, And this is happening just with a particular person when I try to view it. The highlights section is visible on their account when I open it which means they haven't hidden their stories from me, because had they blocked me from viewing stories, I wouldn't even have been able to see the highlights section on their account. What could be the reason for the same?

Hello there, Has anyone have same problem with me? Before this I kinda blocked my friend from instagram (and we have some collaboration posts), but when I unblocked him, and we following each other again, the collaborator post are missing from my profile but still exist in my friend's page. Is there anyway to recover those collaborator post to appear on my feed again? Thank you.

Hello, I have in my archive an old story that was originally setted on "close friends".
Now I'd like to put this story in my story highlights, but in a public way, for everyone, without the restriction of "close friends"....
Is this possible?
Thanks!!

Hey everyone I hope you can help me

So the last 4 days my instagram weirdly changed...

I normally use my instagram by sending dms of memes and videos to my best friends

Normally they are at the top of the list to share with them but now they have all disappeared and I have to search for them all individually.

And some of them now don't even come up with some private pages even though they are apart of that page ?

Any suggestions on how to get then back on the top of my send list.

Cheers everyone
