Recently I was making some flows and - to my surprise - hovering my mouse over a logic card with a tag inside it, the tag showed the actual value it currently had. Now, I don’t know how I did that, but I can’t reproduce that behaviour; hovering over a tag only shows the full name of that tag, no longer the value.
Yes, confirmed, to see those results-actual values tags, you must first run your flow.
What is missing and will be probably not added back is the actually values of all tags, eg. when adding them eg. into flows.
