Appreciate you performing this troubleshooting check @ammugowda84, very interesting, in particular if others report Ad Blockers not based on their plugin environment or WordPress/hosting set up.
Based on these latest update, what you’re experiencing is a local or network level block. While this isn’t something we can address within Site Kit, you will be able to view your AdSense traffic within Site Kit from another device, such as your phone. Alternatively, you can view your AdSense revenue from the AdSense platform directly, even if using your current device or PC, which seems to be triggering an Ad Blocker notice.
If you are looking to troubleshooting what specifically may be causing an Ad Blocker notice on the Site Kit dashboard, you can check the software on your computer, temporarily disabling any firewall or other application while checking the Site Kit dashboard each time.
