Hello,
I have a wooting 60HE+ which I had previously configured to have 2 function layers (layer 1 accessed through Fn1, and layer 2 through TAB, which is Fn2 in the first layer) and was working on windows.
I switched to Linux a while back but noticed only recently that I don't seem to be able to access the second layer functions anymore (first layer works fine).
I'm on Fedora 43 with KDE Plasma and use the Wootility AppImage downloaded from the website. I have followed the guide for udev rules and the Wootility app recognizes the keyboard, lets me see and change the configuration, and my second layer functions are there.
