Doesn’t work on High Sierra

High Sierra has been out for a long time now; this software has not been updated since 2o16. Why is this still on the Mac App Store if it doesn;’t support High Sierra? Logitech tech support gives me confusing and irrelaevant answers about c920 camera support and OS X Logitech OS X software. I am about ready to give my c920 cameras to Goodwill and go with another vendor that can properly support their customers that are using Macs.
