I am currently setting up the AMX ACB-2110, to be used for room scheduling. However I have come across the following issue, When I try to book a room, it all seems to work fine, however, the room booking doesn't then show on the left-hand side calendar on the device's screen. The screen also doesn't go red when the room has a current booking, and the device still says AVAILBLE and the screen stays green. The meetings are showing in my google calendar, so I can tell they are being logged.
Any ideas why this isn't working?
