I use a Windows 7 PC with Thunderbird and a Google account A and a Windows 8.1 PC with Google Calendar and a Google account B in a browser. If I make an event in a shared calendar with an alarm in the W7 PC, the event does appear on the W8.1 PC but the alarm does not appear on the W8.1 PC and vice versa. The alarm does appear on the PC where the event was put in.
Please your advise to solve this problem.
