Facebook Login Error

I have a Blynk app that has been running without issue for months. Last night, when trying to log in via “Login with Facebook”, I received an error: “App Not Setup: This app is still in development mode, and you don’t have access to it. Switch to a registered test user or ask an app admin for permissions.” [image] This error occurs when logging in from multiple devices. If I try and log in with username and password, I am told I must use Facebook. I have not changed anything about my project…
