Why is DTM failing to load its own library, and why in the world would that break my site?
When I go to the provided script link, the script content is returned, so this tells me the script is available but there may be a timing issue preventing it from loading. The script failure shouldn't cause the site to break nor should it interfere with the library loading; however, I'm happy to dig further into this behavior to determine what's going on here. Can you provide the DTM property / rule name and a test URL by chance where I can review this behavior?
thanks for following up!
