The problem was entitlement not being granted to new installations and new users. So, with people creating new installations, they faced this issue. Whereas those that updated their 5.0 Preview 2 seemingly did not.
All 21000 people affected were granted the appropriate entitlements. This was a manual process, so likely, and some people may still face the issue or an issue related but not directly the same.
I appreciate how frustrating it is not to have a tool you wish to use or have used in your workflow, and we are working with folks to get them back on track. We are asking for the Epic ID / Email (in PM) to look specifically at users’ accounts to see what the problem is. If you have taken the steps suggested; Closing all UE applications, restarting the launcher (always good to continue your entire system, we’re all guilty of not doing that enough), and then searching your vault- the please do reach out via PM
Thanks!
