Not a NoScript problem: on that site I had to
1. Set googletagmanager.com to TRUSTED, probably because they use gtag to load most of their further (many) JavaScript dependencies
2. Disable uBlock for the page, otherwise some essential scripts could not be loaded or even shown because were preemptively filtered by uBlock.

If you've got other situations like this please try disabling other extensions (such as uBlock) and report in the proper bug tracker, thanks: https://github.com/hackademix/noscript/issues/
