Update

Hello,

I don’t know if you still want to update this plugin. But with the (new) gutenberg editor this plugin send two notifications. This is because the gutenberg editor has two loops.

This is easy to fix. You need to add the following to the pending_submission_notifications_send_email function:

if ( defined( ‘REST_REQUEST’ ) && REST_REQUEST ) return;

For more information about this see: https://github.com/WordPress/gutenberg/issues/15094

Hope it can help you! For the rest, simple but effective plugin!
