Why must I reload ArduinoCreateAgent-1.1-windows-installer-chrome every time I restart my computer? What am I missing that this is happening?
Used to use a laptop (with Create Agent installed on hard drive) which never had this problem.
Now using a Windows 10 desktop and the On-line Create Agent.
Unless I reload the Arduino Create Agent, I always get the 'No Plug-In Connection' error message, please see screen capture.  Device manager recognizes the Arduino Uno and assigns COM3 to the USB connection, please see screen capture.
Thank you to all who have suggested corrective action for my posted communication problem.  After trying all of the suggestions, I threw up my hands and deleted all evidence of Arduino Create Editor.  Next I installed the Arduino Create Editor as a fresh/new install.  Magically, all of my communication issues with the Arduino Uno have been corrected.  Apparently, something in the communication code was corrupted during my first attempt install on my desktop PC.
