This has been happening a lot for me. Specifically since updating to 115.8.1. I thought it might be related to bug 1809023. I created an event in my Android Google Calendar around 4:05PM CST (version 2024.07.0-608174112-release) to fire off at 4:30PM. Worked fine on my Android device. TB doesn't even see the event existing. For good measure, I restarted TB thinking it might pick up the event per the above bug but it did not.
