Looks like it can' t be reported, instead Meta says they will monitor this forum so we can only hope they do but I guess all we can do is keep this thread active and hope for upvotes so they will notice. Surprised they haven't noticed that this stopped working.

From Meta when trying to report a bug: "Advanced technical support via this channel is no longer publically available for this product. Instead, these issues will be supported via the Developer Community Forum. We believe engagement through the community will aid collective understanding of our products and we are continuously improving the experience on the forum. We will also regularly monitor the forum so to support developers on critical issues facing their business.

We apologize for any inconvenience and welcome any feedback or feature requests related to the community forum to make it the most effective channel possible. Thank you!"
