If you are unable to see an app in the Event App by Lumi Dashboard it could be:
MEA and SEA
The Filter By drop down does not have the Showed Expired licence status ticked. Also check the authenticity is set to All.
The filter by Version status, QuickEvent status and authenticity should be set to all
Also consider which platform its was created on, all new SEA, MEA and QE are created in the .eu platform. Older events maybe be archived in the .com platform.
