The index / noindex is not updating all tags when toggled in the Smartcrawl > Title & Meta settings.
When toggled no index it should set all tags to no index
When toggled to index it should set all tags to index.
Currently it makes no effect on the individual tags. If the setting is toggled to index and you visit the smartcrawl meta of an individual tag it will still show it as noindex in the advanced tab of the tag and in the on page seo meta
Could be a bug – not sure what the intended action of the toggle was supposed to accomplish
