Hi I am trying to add a new brand to my account, I only want to add Instagram for this new brand.

When I click add new account then choose Instagram it redirects me to connect through facebook like normal,
Then it gives me the list of available accounts but is not showing my new brand?

I do not have a facebook page for this new brand and do not want one, it’s just Instagram only, but I have connected it to my facebook account
Why is it not coming up in the list and letting me choose it?

Many thanks
