Facebook GD Restriction

Hi, this week I received an email from Facebook indicating:

n working to create a great Platform experience for everyone, we ask developers to ensure the apps they build comply with our Platform Policies. Your app GD (AppId: 11975XXXXXXXXXX6) doesn’t comply with the following Platform Policies:

Platform Policy 8.3: Use a clearly branded “Login with Facebook” button and follow the Facebook Brand Guidelines: https://www.facebookbrand.com/.

Your Login button doesn’t properly reference Facebook. To fix this issue, you should always use our official SDK for Login. For more information on Login best practices, check out the Login section of our developer documents: https://developers.facebook.com/docs/facebook-login/best-practices#buttondesign.

Since we’re striving to improve the Platform experience, your app’s ability to do the following has been restricted.

– tos

Once you’ve updated your app, please go to https://developers.facebook.com/appeal to appeal. A member of our team will get back to you within 48 hours.

I followed the instructions from https://wpgeodirectory.com/docs/social-importer-addon/#facebook when setting it up.

Do you have any suggestion on how to fix this issue?

Thanks,
Eduardo
