Hi andrejsto ,
Thanks for reaching out to us!
Could you maybe try the page rule debug function to see why the page rule is not triggering?
You can find the page rule debug by going to the Page Rules dialog.
Then click on the three dots menu next to the page rule name and select Debug.
From here you should be able to fill in the url. To test the start page, simply leave it as it is and just click on Debug page.
It should show you why it's not triggering on the start page.
Could you maybe send us a screenshot of the results?
Also could you check if the received values were correct?
