It would be great to be able to copy text from read only events (events which you cannot edit) on Android. Sometimes it is needed to copy event description or meeting link, but it is not possible to do so on the events which you cannot edit.
It looks like on Android 13 all the options under Hour size setting (Small, Medium, Big) doesn't really reflect the size of the hour in Daily and Weekly views.
Being able to show a location-based (preferably a set location that can be changed for any given day (for example when working away or on holiday) rather than a live location) sunrise and sunset time on the calendar would be amazing.
Off line Outlook within MS Office on my PC should be able to seamlessly synchronise with my Android phone without having to give all of my information to Google through their Calendar app(s)
I honestly don't know if this is the app or a system setting, but when an appointment comes up, One Cal pops up the reminder, but only for about 10 seconds. Sometimes it switches to "missed" before I get the phone out of my pocket.
