This typically occurs if you have multiple Instagram accounts linked to one Facebook Page.
In order to resolve this issue, we recommend completing the following troubleshooting steps:
- Delete the app
- Re-download the app
- Open the app and click ‘Login with Business’
- When the following prompt appears: “Vamp wants to use Facebook to sign in”, click ‘Continue’
- Select ‘Edit Settings’ on the screen that says: "You've previously linked Vamp to Facebook"
- When prompted to select which account you want to link with Vamp, only choose the one you're trying to log in with
- When asked to select pages, choose the page your account is linked to
- Click ‘Next’ and then ‘OK’
- After you select your account, you should be able to log in as usual
