I have 2 calendars in Google. Although both are checked and are shown to be synced on the tablet, only the events of one of them actually appear, while the other calendar events are not there. I can add new events in that calendar, and they sync and show up both in the tablet app and in Google's calendar in firefox, but I can't see events created in firefox on the tablet. Both calendars are syncing perfectly on my Samsung phone. Is there anything I can do about that?
