Some MCC users are reporting that Google Ads Advisor, the new AI chatbot, is mixing context between different client accounts. Advice from one advertiser chat is showing up while chatting inside another advertiser’s account.
David Melamed flagged the issue, noting cross-account business context leakage. Google Ads Liaison Ginny Marvin confirmed the team is investigating.

If you manage multiple clients under an MCC, proceed carefully. Ads Advisor may confuse account contexts until this bug is fixed.
