Stop using gtag 'update' for consent which is too late for some cases, causing tag to fire before consent data is collected. Switch to use Consent Initialization trigger which make sure that tag only fires after consent data is collected.
Minor changes
By default the app provides Google consent mode V2 (advanced mode/basic mode), which could be enough for many markets.
This version introduces Consent Strict Mode, in which GTM is only loaded when consent is given for at least marketing or analytics permission. Some regulatory (EU) might require this level of compliance - despite the popular arguments that the tag manager does not do any tracking, but only the tags that it manages.
Strict compliance means you would have zero vision when a customer opt-out. Consider it stricter than the Google Consent Mode V2 basic mode.
