I applied my custom VF page to a global action, works perfectly internally, however, when using the community the page does not display. The page has been checked for displaying on mobile, permission have been set for all users and even tried to redirect the URL but no luck. The same page works on desktop though.
When debugging the page, I noticed the following error:
GET https://sandbox-campus.cs16.force.com/apex/AccountViewMobile?id=001f000000H…FrameOrigin=https%3A%2F%2Fsandbox-campus.cs16.force.com&sfdcIFrameHost=web 503 (Service Unavailable)
The path should be sandbox-campus.cs16.force.com/Office/apex/ or .../Office/
Could anyone explain why the page does not display on the community version of Salesforce1 app?
