When I try to open Rush 1.5.20 it prompts me to access my "public" folder in system prefrences>security&privacy. When the preferences pane opens there is no "public" for to grant permissions. Rush will not open without this. Operating with macOS 10.15.6. What to do???
Very sorry for the frustration. I wonder if you had any issues using Rush on any other devices? Have you tried the mobile experience? Does it give you similar permission errors?
