@bvarvel: Hello there, If you were using tag support for a Personal Account, the feature to make use of tags for a personal account has been removed by Instagram. You can only use Instagram tags on Business Account from now on. For that you will need to have Business Instagram Account and also a Facebook Page which needs to be connected to the Instagram account. We are working on this feature and waiting for an approval from Facebook. For more information please follow this link.

I hope this helps you out!
Kind Regards,
