I have tried some apps that create an iCloud drive folder. After I delete the app the folder still remains lingering and I can view via document picker or iCloud.com I have tried some suggestions by re-installing app, disabling iCloud drive toggle for that app in settings and then removing/uninstalling the app but the folder keeps coming back. Does anyone have a solution as I have not been able to get rid of these. As time goes on, I could have dozens of useless folders. Apple really needs to allow us to go in and cleanup iCloud drive at a lower level to remove some of this junk.
