Rated 3 out of 5 stars

Issue 1: the red "current time" bar on the week-view calendar is about 30 minutes late, compared to the actual time. E.g., my time now is 10:11 am, but that red bar looks like it's only almost but not yet 10.

Issue 2: I can't customize the calendar tool bar. Every time I restart Thunderbird, it rolls back to the default.

No above issues before updating to 68.

This review is for a previous version of the add-on (68.0).
