I am getting a message saying that for Google, Universal Analytics will stop working on July 1st 2023. It looks like the CS Cart add-on is based on the UA and not Google Analytics 4 (GA4).
What can I do to ensure that the add-on is compatible with GA4?
The current add on is compatible. Simply obtain your GA4 id and insert it into the add on settings.
Did you test it? In the source code of the built-in module I see only Universal Analytics code
We have implemented addon with few features for much more better accuracy and with support of old versions of Cs-cart
