I've been setting up BTT in the last two days with my Macbook Pro 16", and have noticed an issue where the calendar widget will not show any events that aren't a part of my "main" calendar, I.E. synced iCal subscriptions. I'm using Aquatouch, but the issue was persistent before I installed the presets. I found an old help thread that instructed to install iCal Buddy, which I've done, but the issue remains. Any advice would be appreciated.
