Have you gone to tag a product in your instagram post and got this error?
Your not alone. As of Saturday 26th of September 2020 a wave of Australian businesses found that they couldn't tag products on Instagram.
I had a chat with Facebook support and found out it's a widespread problem in Australia. It's not yet resolved.
Facebook has been rushing out it's updates to Facebook Commerce and have broken some things in the meantime.
So - hang tight and hopefully Facebook releases an update sometime soon.
