I have a scenario that has worked for quite some time to post to my Facebook page.
On Dec 20, I started to get the error below but had changed nothing in the scenario or on my FB Business Integrations. I have removed and re-added the integration several times but with no success. Is anyone else seeing this? If so, were you able to resolve?
