Hi all,

I am new to Power Apps Portals and have become stuck at 1st hurdle. I have a test website I am trying to edit, when I click to edit the Portal App (image 1) there is an error message "unable to load preview" (image 2)

there is an older post this year (link below) with the same issue. The fix was to modify cookies to allow 3rd Party Cookies which I have done but does not fix the issue

Hi @Docs
