The latest update to remove GTM injection is a disaster. I was using that feature everyday in my job to build containers for clients. Is there anywhere to download a version of the extension that still has it?

Big thanks for the update; because of the new API in Chrome, the previous version was deprecated and removed. I had to find other alternatives, but they are all terrible compared to this extension! It works perfectly so far.

Stopped working after the update. Just keeps on loading god knows what. They decided to revamp the whole thing and at the same time remove some features which I frequently use. Awful.

One thing is missing.. configuration of dataLayer object variable would be appreciated.
Otherwise looks good.
