Was about to post the same issue. Events are updated only in editor almost at once when I add it to Google calendar, but main wallpaper stays untouched when I save th editor. To see added event I have to either change wallpaper to some other and come back or restart my phone. Not to duplicate but have you found a solution to that?
No, just a workaround and it’s quite heavy. As I mentioned - $ci(title, i)$ (without date) works perfectly fine. So for each day I add all the events from 0-19, but then I hide all the events with a different date that I want.
