Era mucho más útil la otra extensión
fenomenal
There was absolutely nothing wrong with the old tag assistant extension which simply worked. This one is extremely glitchy, unreliable and undocumented.
woooow NICE STEP FOR EVOLUTION!!!
I've noticed that the "Tag Assistant cannot connect" and "Google Tag not found" issues often occur when there's a mismatch between the Chrome user account and the Google account used with Tag Assistant. After troubleshooting for about 4 hours, I found that logging into Chrome with the Google account associated with GTM resolved the issue. While it's not yet clear whether the root cause lies with Chrome or Tag Assistant, further investigation is needed to determine the underlying problem.
This is just a glorified bookmark, taking you to https://tagassistant.google.com/
Haven't been able to connect to any client sites using Tag Assistant for about 2 weeks. Google refused to help me and told me to go find YouTube tutorials, as though I simply didn't understand how to use it. Finally, I disabled this extension and Tag Assistant is connecting again!! I've lost 10-20 hours troubleshooting and it was just this extension. I'm using MacBook Pro latest version and Chrome latest version. Chrome is also constantly crashing lately...
Schwachsinnig...Anfangs hat das Tag perfekt funktioniert...Nach zwei Wochen geschaut...NIX...Hat einfach den Geist aufgegeben...Tag wird nicht mehr erkannt...Einfach so...Und nu? Tag Manager gestartet, Debug Mode gestartet...Läuft nicht...Tag löschen und neues erstellen...FEHLANZEIGE...Danke Google, hast du toll gemacht...NICHT...[Rezensionen werden nicht von Google überprüft...Hat in diesem Fall eine gewisse Aussagekraft... ;-)]
Update: The issue might be specific to Chrome on Windows, as the tool was able to detect the tag installation on Chrome on MacOS. When I tested it, the data layers were also fired up correctly. I will update the star rating when this issue is fixed. I hope this helps the developers and other users facing non-detection issues. Thanks. This doesn't work at all. I have tried installing Google Tags manually and using a plugin. When I view the site's source code, I can see the tag properly installed, but the tool doesn't detect it at all. I tried all the possible solutions provided in their documentation to no avail, and there's no easy way to contact support, just like with all other Google products.
Very convenient and easy to use!
