Hi @jubilo!
Thanks for reaching out. Happy to help you with this!
I want to sincerely apologize for the connection issue with the Facebook for WooCommerce plugin. I’m truly sorry you’re experiencing this across multiple sites. We have identified that there is an issue and are taking it seriously, actively investigating with the Facebook team and providing them all the information they need to troubleshoot this further.
We are working very closely with the Facebook team to troubleshoot these connection errors. A Facebook update is required to resolve the issues, and our plugin team is working hard to provide details to help resolve this.
In the meantime, version 1.11.4 uses a different connection process, so you can roll back to this version if needed. This may result in needing to adjust some settings when you upgrade again in the future, but you can download that version here.
Thank you for your feedback,
Benjamin
