“do you consistently visit at ten minutes to midnight or something of that order and then see that day view has already advanced to the next day? If that’s the case then that would be useful info for us to progress this (and I do hope my question doesn’t sound facetious – I just want to ensure I’ve got a clear picture)”
The calendar changes around 8pm each and every day. Also, I have the “End of day cutoff” option set to 7am in the plugin settings. Not sure if that has anything to do with it but all I know is that my calendar switches to the next day around 8pm each day. I currently have the calendar view as “Day” and have not tried any other view to know if happens with other views selected.
