Hi @lovingbro !
Thank you for your reply.
Here is the System Status Report: https://gist.github.com/jbast1/115df2c14321bd02213893fa881b7773
After investigating a bit more, I realised that the issue is coming from the official Facebook for Woocommerce plugin.
Is there something that you can do on your side to allow us to keep using this plugin ?
Thank you in advance !
