I'm a Citrix consultant by day, so I'm often in customer environments doing things..
I notice that with Quick Access it doesn't always clear the clipboard in the remote session and replace it with a password I've copied from it
To get around it I've just been pasting the password into notepad, on my local device, then copy/pasting from notepad into the remote session
If I haven't copy/pasted anything within the Citrix session then quick access works as expected
