Hi There,
Actually I’m seeing 3x PageViews events ad I’m using to see in Analytics.
This is my setup:
• inject piwik container using GTM on All Pages Trigger
• Piwik Pro Tag is set to ‘Track Page View manually’
• I’ve added a Virtual Page View Tag on a custom event (nuxtRoute)
With the Piwik Pro debugger I see:
• 2 pageviews on Home Page (Piwik Pro + 2x Virtual Page View)
• 1 pageview when browsing virtual pages
• 2 pageviews every time there a ‘real’ load of another page (Piwik Pro + 2x Virtual Page View)
Can’t understand why the PageView gets triggered two times
Help! 
Francesco
