Plugin can’t see the instagram account

Hi there, I’m trying to connect an instagram business account as I’ve done before with the various webpages I manage. I have access to the instagram account on business manager, but when I connect the plugin and select “access all my accounts”, it doesn’t see the account I’m trying to connect. Other accounts I have in my business manager is listed except this one. Strangely enough, it does see the facebook page of that account in the next step. Any idea how can I fix this? Thanks in advance.
