Thunderbird (local) calendar notifications for events are partly not working

I got a new PC with Windows 11. I installed Thunderbird 136.0.1 , activated the private calendar, and entered events there. For events with a reminder that have a specific duration (e.g., Wednesday from 10 AM to 11 AM), I receive notifications. However, when I create a full-day event and want to be reminded, for example, 1 day before, I don't receive any notification. Additionally, events with a reminder are not shown in bold in the calendar overview (whether they have a specific duration or are all-day events). Can you please help me?

The issue persists with version 137.0.1.

Further testing has shown that I only receive notifications if the computer is turned on at the time of the alarm. For example, if I set a reminder for an event at 10:00 a.m. to trigger at 8:00 a.m., but I don't turn on the computer until 9:00 a.m., I do not receive the notification. However, if I turn on the computer at (or before) 8:00 a.m., the notification does appear.

The issue also occurs on other computers.

A prompt bug fix would be appreciated.

Thank you for the update. There is a rewrite of part of the front end coming, in a few months I think. But I'm don't yet have enough information to say whether this will be fixed then. The good news is calendar progress is being made.

I am also experiencing the problem with my Thunderbird Local Calendars. I am receiving no reminders at all on V138.0.1. This is extremely frustrating as I rely on reminders to get work done.

v139.0 seems to have fixed the problem. Thank you! :)
