Thunderbird 102.1.1 I'm subscribed to my Google Calendar and also checked off the shared calendars Holidays in United States and my wife's Calendar. Recently my wife's calendar stopped updating. I can see events she added a few weeks ago but nothing she's added recently. As a test we both added fake events for this evening then I forced a sync. The event I created appeared in Thunderbird but hers did not. I can see both when I visit calendar.google.com
