This is an issue we are working on with MS.
- Search for "Powershell"
- Run it
- Type Get-AppXPackage *ParadoxInteractive* -> 'Enter'
- For each owned game you should have a list of DLCs in the Dependencies field.
- Confirm it has entries you would expect to have (it should match with what you own, so if you bought Stellaris Utopia you should see it there)
- Type licensingdiag -> 'Enter'
- Wait a little bit
- You should see a folder with a .cab file being selected. Please attach that file here.
