Hey @leadswithliv there’s an existing Manychat account connected to your IG profile.
You either logged in with another profile (maybe connected to Facebook or Gmail?), or someone else connected the account.
If you can’t figure out where the other account is, you’ll need to talk to support so they can help you either gain access to the other account, or disconnected and connected to a new one, etc.

Make sure to give them as much information as you can about the accounts so they can track you down.
