Hi @maildeepak thanks for your question. If you already have Site Kit enabled and Analytics connected either via the Analytics module or GTM module then this should be tracking your Web Stories.
You can check this by going to Stories > Settings > Google Analytics. If this is configured correctly it will say “Site Kit by Google has already enabled Google Analytics for your Web Stories, all changes to your analytics tracking should occur there.”.
If this isn’t set up then you should be bale to just place your original Analytics property in this section of the Stories settings.
If you have any further questions let me know.
i removed Site Kit plugin and added the GA3 property ID via Web Stories settings.
