The platform makes use of a cross-site tracking mechanism (to communicate between the new platform and former Insight) and the user's browser settings block this kind of tracking.
The user should check his/her browser settings and (temporarily) allow cross-site tracking. Check the examples for the browsers Safari and Chrome on how to do this.
Navigate to Privacy
Uncheck the box next to Prevent cross-site tracking
Navigate to Advanced > Privacy and security
Go to Site settings
Go to Cookies and site data
Switch off Block third-party cookies
We will optimise this cross-site tracking soon and by then this problem should not occur anymore.
