Hi
Yes I have this exact same problem also, I have only noticed this since the last update. I haven’t plugged the usb out to resolve, I have restarted the app or daw and it is fine after that. This happens when I connect the mac to the SQ5, my mac is usually on already but the issue doesn’t occur all the time.
I am using a MacBook pro retina late 2013 running Mojave 10.14.4.
