Internal error when importing UA to new GA4,& unable to connect GA to Site Kit.

Initially, I encounter an internal error when attempting to click on "import UA to GA4." Subsequently, when I try to finalize the connection to GA4 in my WordPress Site Kit plugin, GA fails to connect.

Hi,

As for the site kit, you can post on the plugin support forums for assistance with this (Link - wordpress.org/support/plugin/google-site-kit/#new-post). As for the GA4 internal error - check if the GA4 snippet is added (go to webpage and right click --> view source. Search for your GA4 id here). If you have installed GA4 with GTM, then use Google tag assistant( tagassistant.google.com/) to check if the GA4 Configuration tag is firing
