In adobe tag manager it is very difficult to manage tags on different
environmnts (dev,stage, prod). Unless someone is adding very in detailed
comments you can not really comment about current state of tags in any
environment . Even none will take the risk of pushing something to
production environment without checking all the tags just by relying on
someones detailed comment. To solve this issue adobe should really add
feature available in many versioning tools i.e. ability to compare and
merge...
