Hello. I am a t-bird user and have just installed the add-on called "Provider for Google Calendar". It works well regarding events (creating and deleting them both ways), but when it comes to tasks it doesnt work. When I create a task in t-bird calendar, it doesn't show in the calendar, neither t-bird nor google. But it's possible that the task is in fact created because in the mini-calendar in the upper-left corned the day numer becomes bold, suggesting there is a event/task assigned to that date. Task are also invisible in the Google calendar. The exception is when I create a task choosing 'my task' calendar in the process. Then the task created still does't show up in the t-bird calendar, but it's visible in google calendar. Strange. Can you help? I'm not attaching pics, because it would take a video to explain it. I also use Thunderbird in Polish.
