I did reinstall the app and now I see the “Apply Changes” and “Undo”. I do have three other computers where I will test this beta version. I’ll let you know if there are any bugs
I did installed in another Windows 10 machine, build 16299.125 and I didn’t need to reinstall the app to see the “Apply Changes” button
This machine has no domain while the previous laptop is part of the domain, after that those are pretty much the same with the same programs installed.
