Imported device calendar events are not listed by time

I’ve tried sorting every way, and my device calendar events have to be manually sorted to show them chronologically. (I tested both 12 and 24-hr time.) Not sure if this a bug or a feature request. I have been looking for an app for my partner to help him get organized, but I am afraid w/o this it would be unusable for him. I quite like this app myself! But I would never consider the premium version w/o this feature.
