No, I haven't linked the IG account to any other account in the past.
When I try to synchronize FB with IG, my IG profile picture shows up on the menu bar next to my name.
Though, when I press cancel it disappers and I return to the main page.
I have installed the Facebook Login app and have Instagram Login Handler app(in Sandbox mode).
The problem is that when I login to the website with Facebook and then try to synchronize it with Instagram, I get the
following message: Your Instagram account is already associated with another member.
How do I get around this error message?
