If Google Analytics code somehow does not work on your website built with Betheme, please do the following:
1. Check Site Tag Manager
Make sure, you put complete site tag manager and not just ID. Global site tag, supposed to look like
2. Disable 3rd party plugins
If you are sure about Site Tag Manager, please disable all 3rd party plugins. We know from experience that some plugins may overwrite theme options. If this helps, you can turn them on, one by one, to find the culprit.
Quick Tip!Google Analytics field is located under Betheme > Theme Options > SEO > General section.
