I have started using unity to develop AR app and I seem to be having an error in the c# script of my project. "The type or namespace name ‚ARSystemStateChangedEventArgs‘ could not be found (are you missing a using directive or an assembly reference?)" is the error message displayed. Please help. submitted by /u/shs2410 [link] [comments] Augmented Reality & /u/shs2410 15. September 2020
