I'm posting new thread for this topic because other threads with the same topic did not provide any information to solve my problem. I coded the Kill App as explained in the video of the same name. The Kill App works fine the first time I use it. It Force Stops the "test app" and returns properly to Tasker. When I then use the Kill App to Force Stop "test app" after I've used "test app", "test app" is Force Stopped but Kill App does not return to Tasker. It appears that the Autoinput Global Action Back is not working. The incorrect behavior keeps occurring until I restart the phone. Once I restart, I get the correct behavior the first time I use Kill App to Force Stop "test app" but then get the incorrect behavior until I restart the phone. This incorrect behavior happens for all apps I try such as AccuWeather, MailDroid, Resound 3D, etc. I'm using a Pixel phone with Android 8.1.0. Any suggestions for fixing the problem are greatly appreciated.
