I'm a new user of mx keys. I'm using on mac 12.1, when I press any of "Mission Control", "Launchpad", or "Show Desktop" pre-assigned buttons, they randomly stop working; after awhile they work and suddenly stop working again and again. If I set keystroke to CTRL+UP for mission control and FN+F11 for shop desktop via logi options, it works very well. Please fix this issue as soon as possibly. I paid 1400 TRY for this keyboard.
