I love Logitech gear (I use the G900, 933, 910, and 600 peripherals) but I'm not impressed with the one app that lets you use all the features of their gear. The app looks dated to 2010 and there's no cloud storage for your profiles to sync between devices (which is a shame for those of us with laptops and work computers), and sometimes it's buggy. For some reason my computer has to ask me for permission to let my phone connect every time even though I tell it to remember the permission. Not that great but it does get the job done. Please overhaul the UX on mobile and desktop, Logitech.
