hello-gos The Gmail app is compatible with all six per-app exploit protections without warnings currently (for me at least), but I didn't see any setting in the app to stop the automatic rendering of previews of attachments, especially for messages that are in the Spam folder (such as if Gmail detected them as a phishing attempt! this is very stupid). The Gmail app communicates with Google Play services and is installed from Google Play Store, both of them require disabling the DCL exploit protections. Look for compatibility with exploit protections, settings to harden the app such as blocking the preview of attachments either in the Spam folder or completely, etc.
