I’m facing an issue on Tag Manger where the preview mode is not displaying. I checked other post about similar issue and I tried all advices to make it work properly as to clean browser cache, to test different browsers (Chrome, Firefox and MS Edge), uninstall all extensions from the browser, to test in a incognito window and to test in different desktop devices. Nothing is working!
I know the Tag I published is working because I can see visitors been tracking on real-time report but I can not test or validate any new tag on Debug/Preview mode before publish anything.
What else can I do to make it work?
As additional information, I’m running Matomo 4.1.1 on a IIS 10 with PHP 7.3.8. It is tracking a website developed in .NET.
