Is anyone seeing the Quick Assist bug with a tiny window, can't resize?


I use Quick Assist 2-15 times a week at the office. In the past seven days, every second session, it's connected in a TINY window, about 320x240 resolution, and I can't maximize the remote session to see the screen properly. Any way to fix this?”

Quick Assist Transfer Files

Typically, Windows Quick Assist does not offer the option to enter the full-screen mode as RDP, for instance. So Quick Assist full screen is not possible. But If your screen resolution is more significant (in both dimensions) than that of the screen connected to the machine you are supporting, then you scale the screen to a proper size.
