I was wondering how I can enable smart tags on AEM 6.2 SP 1? I have read the documentation here: https://docs.adobe.com/docs/en/aem/6-2/author/assets/managing-assets-touch-ui/smart-tags.html but it does not say how to enable the feature, just how to enable for specific folders. However the checkbox mentioned is not shown on my AEM instance.
There is a procedure in this topic that discusses how to set this feature at the folder level.
I see the same issue. This is a bug. Please file a day care ticket and specify that the documentation is wrong.
