In some isolated incidents, users were who were editing existing campaigns encountered an error pop-up. This issue was derived from a case where advertisers with expired Google Analytics versions (specifically UA) included in their web connection type saw this error as a result to safeguard historical connections and avoid removing historical data backups.
We have implemented a fix to update the validation logic to ensure we address an edge case of UA+GA4 advertiser to allow campaign editing (when GA4 web data remains connected).
