There must be some issues with Manage Scans. It seems that you can't manage them. You had better set a scan up and let it run after installation of BIS. After I had rescheduled or changed the settings, it stopped working. Even if you restored the settings to the default values and stared setting something up from the scratch, it no longer works. The same thing happened in BIS 2019 as well. I was wondering if there was anyone else encountering the same problem.
