I have an installation for K2 5.8 + SharePoint online.

For any K2 URL (for example for an approval task form or a simple SmartForm viewed directly from SharePoint online as an iframe) when an user arrive for the first time, K2 is showing a “Please login” popup with the following message: “We must create a token on your behalf - click here. Once the token is successfully created, click OK to refresh this page.”

This popup asks you to create the OAuth token. Clicking on the link “click here” is opening a new browser window and you need to close the window and refresh the original page.

This is not a friendly behavior. It is some fix / alternative configuration for this?

Thank you
