Migrate to allowlist and blocklist

This will likely not happen in the 8.x-1.x version, but has been changed as part of the upcoming 2.0 version. According to Google, they won't be removing the old parameters so there isn't a technical need to move away from it in a minor release.

I'm getting so frustrated with this damn Module.

After suffering a 5 month Google Analytics outage due to the Consent Mode bug, I discovered that most tags in Google Tag Manager have not been firing since we installed 2.0.5 to resolve the earlier outage.

It looks like all variables are wiped out when a GTAG command is sent to the datalayer. The command involves the allowlist and blocklist.

Because the variables are all undefined (and never recover), Tags can't operate.

I spent about 8 months in 2024 trying to resolve Google Analytics problems as a result of the Google Tag Module. This is ridiculous, and Acquia and Google are absent, clueless supporters.
