There is DTM being used on a site. Could Launch also be on the site at the same time? And would data collected from Launch go into a separate report suite?
You could do it, and data would g where you point it.
But not a great idea to put any two tag managers on the same page. It may interfere with each other and cause problems
No, you can't use DTM and Launch on the same page.
Both DTM and Launch use the global variable window._satellite. So, whichever library loaded last would overwrite the other and things would break.
