You can check in your Facebook Business Integration settings here to see if Node is currently connected to your account. Here you can also disconnect or remove Node from your Instagram/Facebook account.
If you're having login issues, we would recommend removing Node from your integrations and signing-in through the app again.
Note:
Don't worry, doing this will not delete or change anything with your Node profile. It would just allow the app the reauthorize your account when you sign back in.
