I previously has Logitech Options installed. After I installed the Logi Options+ software, I was surprised to see that the Logitech Options software was still installed and available via Windows' Programs and Features dialog.

I would have expected, at least in the full release version, for the new software to identify this situation and manage that in some way (such as by prompting to uninstall). If there are legitimate reasons to have both programs installed, you should think about how best to communicate this to end users.
