As known issues are identified after the Release Notes are finalized, those issues will be listed here.
Issue: ATP Host Integrity and Quarantine Firewall policies are auto-applied when EDR 2.0 is enabled. Solution: Symantec changed this behavior in ATP 3.0.5. Upgrade to ATP 3.0.5 before associating ATP with a SEPM Controller connection to prevent this issue. URL:https://support.symantec.com/en_US/article.TECH248959.html
