Installed the Options+ software and found the procedure satisfactory and the interface functional. I use an MX Keys with MX Ergo (not supported yet) trackball.

I had no issues resetting my custom key layout, and since the UI displayed my trackball, I clicked on it and was rewarded with the dialog allowing me to use Options with a link. However, that link only opened partially and finished with a black screen. After a few attempts, I opened Options manually and found that the Duo button was gone, even though it displayed my MX Keys.

This has happened before, and required a full uninstallation and reinstall of Options software. In the past this has restored my Duo button for using the fn key to add additional functionality to the MX Ergo. This no longer works to regain that functionality, apparently due to the Options+ software running.

So while pleased with the promise of Options+, I am concerned that the pairing may be lost due to the MX Ergo not being the latest. I'm currently using my 2nd purchase MX Ergo and, like Windows 11 will not be running out to purchase a new laptop or trackball.

For now I intend to use them both as allowed to configure to see what develops on Logitech's end. If it ends with the new software only for the MX Keys it will defeat the entire purpose of the pairing with the MX Ergo to use with multiple devices, defeating my need to keep the MX Keys and loss of investment. I will be a very interested tester to see how this goes.

I have older Logitech devices (Mouse, keyboard and even a T650 trackpad) still in use, and have experience to expect my current investment to last more than a couple of years. Here's hoping you guys get it all right, and you seem to be off to a good start! Thx, Stan
