July 2021, Win 10, maybe to help a few GS911 users save a little time. I had all sorts of issues when i updated to the new firmware. several hurs of wasted time trying to fumble through a multitude of issues. What I ended up doing: delete to GS911 app from my laptop. Go to the GS911 website and download a fresh copy. After I did that everything work better then usual. I like the new version. been a loyal GS911 customer for 10 years but honestly their update process is never very smooth. Every update brings on a host of issues but eventually work themselves out with painstaking troubleshooting
