Hey, Faye, I went into my IG profile and there's actually a check box with the following text next to it:
Include your account when recommending similar accounts people might want to follow.[?]
When I click on the [?], it says on the linked page:
"Keep in mind that when you opt out of account suggestions on your profile, you won't appear as a suggestion on someone else's profile either."
Do you have that box checked? Maybe you should try unchecking it.
