If onbrand keeps connecting the wrong account, first log in to the correct account on the social platform itself, then open onbrand in a private/incognito browser window and connect from there. A private window won't reuse your cached cookies, so it won't sign you into the wrong account automatically. This is the fastest fix for wrong-account connections on any platform.

Before trying again, make sure:

• You're logged into the correct social account
• Your account meets the platform requirements (account active; Instagram Professional + Public; Facebook a Page you manage with Admin access)
• You refresh the page before reconnecting
