  On July 14th, 2020, Chrome browsers will be changing their behavior to enforce more privacy-preserving defaults for cookies called SameSite. A similar plan is already in place for Microsoft Edge and Firefox browsers, all supported by Oracle Fusion Cloud. (To find out which browsers are supported by Oracle, please refer to our System Requirements page).

While using our Fusion Application Cloud, if you have:

  1. Embedded contents from external third-party applications or to Oracle PaaS based applications (e.g. JCS) from Fusion application pages using a "Web Page" through Page Composer Customization,

  2. or, you embedded these applications by creating new pages using Page Integration,

   And the embedded contents have different host than fusion application host *,

then you may face problems when the Chrome browser roll out this default. For more information on this topic please refer to this article.

Application pages, that were rendering fine before, may suddenly stop rendering after this latest Chrome browser upgrade. Additionally, you may be able to successfully access your application using its direct URL in the browser, but will be unable to access the same application from within Fusion Cloud.

Additionally, the issue may be reproducible using Chrome, but not with Firefox or other supported browser.

Steps to reproduce:

1.  Embed 3rd party application within fusion application through page integration. Navigator -> Setup and Maintenance -> Manage Setup Content -> Manage Integration of Additional Applications -> Create

2.  Access the 3rd party application using Chrome browser version 84 or higher.

At the left bottom section of Chrome browser, the user will notice the access URL is constantly refreshing but the embedded page content is not being displayed


Chrome was upgraded to a version that has default settings of SameSite = Lax or Strict
