Cannot add multiple links in bio

I know that Instagram released a new feature where you can now add up to 5 links in your bio that are clickable. For some reason, I still can only have one link. I have a business account but just don’t see a button under links (per YouTube tutorials etc) where I would be able to add a second one. Has this featured not been rolled out yet everywhere?

Also, you’re supposed to be able to give links a title, so that the link doesn’t show as www.apple.com (which is ugly) but instead something like “Homepage”. I know this exists for stories and I use this all the time but for some reason when I add a text as the caption of the link, Instagram just ignores it and simply shows the URL. Not sure if my app is bugging or whether I am restricted in any way.
