Same here. Using the apt-installed version (3.36.2). It seems to connect intermittently. Some days it works fine, other days, it doesn't even acknowledge that any of my Google calendars exist, with nothing in the calendar menu and Manage Calendars window except the default locally-stored file. The other day, it was blank. I left it sitting there for a few minutes and suddenly my Google calendars appeared. Yesterday, it was showing the Google calendars all day without problems. Today, it was blank again. I left it sitting for quite a while, and it's still blank. So it's really very random.
