Hi, I've just installed the Google Provider add-on, and without problems imported a few google calendars into the Thunderbird (78.4.0) calendar. The problem is that if I (re) start Thunderbird, the calendars don't automatically display, neither in the calendar tab, nor in the Today pane. To make them visible, I have to open the calendar, and then "hide" them (even though they are invisible) by clicking on the eye to the right of each calendar, and then make them visible again by clicking again. Then the calendar displays, both in the calendar tab and in the today pane. Is this a bug, or is there a setting I'm missing? Help appreciated! Justus
