Does not work for me either. Windows 10, unity, ultimate, 5e rule set v3.3.11. Dragon of ice wind peak module. All purchased through Smiteworks (vs Steam, etc.). Campaign and modules load fine on gm computer, unavailable find campaign by player with demo license.
Edit: Able to make this work. Campaign was identified bu GM username instead of DM “call sign” in the server. User error. Oops.
