Hey Jovan,
Thanks for flagging this - sorry you’re hitting this glitch!
If your Google Calendar was syncing fine before and just recently stopped, we’d recommend the following through the webapp:
Disconnect and reconnect the calendar:
Go to Profile (lower left end of your screen) => Profile Settings
Scroll down until “External calendars”
Click the 3 dots “…” next to the “Google Calendar” and press “Remove.”
Then, reconnect your Google Calendar and it should be up and running again. (guide here)
If it doesn’t work on the first try, sometimes it takes a second or third try.
