Problems rounding a single corner
Greetings all. New to Illustrator here, I'm using it through Creative Cloud on Windows 10, help says my version is 21.0.2 (64 bit). I've been trying to work through a tutorial on using the basic shapes tool, and have been unable to round a single corner. I have the corner rounding icon on each corner, and altering any of them alters them all, I'm unable to do just one corner.
I've tried to Google the issue, which led me to believe the issue was that I had version 17.0 instead of 17.1 to use Live Corners. Creative Cloud would say that my version was up to date and would not go to 17.1. Based on one suggestion I found, I uninstalled Illustrator and reinstalled through a direct download rather than Creative Cloud. When I reinstalled this way, it moved me to version 21.0.2 (64bit). I am still having the same issue though, and can only round all corners, not one.
The shape I'm trying to alter is a triangle made with the Polygon tool. I am using the Direct Selection tool (though I did try the regular Selection tool as well). I am running Windows 10, and my version of Illustrator is paid, not a trial, if that makes a difference. Any suggestions on how to get this working would be greatly appreciated. If you need any other information let me know and I'll respond ASAP. Thanks in advance!
