The app doesn't sync properly - day-by-day-calendar/feedback GitHub Wiki

First of all, check access to the internet.

Secondly, check the settings in your device (your Google account). There must be two options checked for sync - Calendar and Day by Day.

Make sure the account is turned on as active in the left menu of the Day by Day app. Secondly, open the left sliding menu in Day by Day settings -> section Active calendar -> make sure the calendars you need are checked for visibility.

Tasks section - the account must be selected.

Check the right sliding menu as well - there are calendars and task lists to turn on. Here you can read more about the right sliding menu and profiles. If you press on the pencil icon in front of calendars in the right sliding menu, you can check the sync of calendars over there too.

Do the same with the section Task lists in the right menu.

In case that doesn't solve the problem, open the default calendar app in your device and check if the calendar is checked for visibility over there. Sometimes (on some devices) the default calendar does have influence, try to check them on/off and see if that has any difference on sync in the Day by Day app as well.

After you checked everything mentioned above, go to the app settings -> Sync option (left sliding menu). That’s a forced synchronization of calendars and task lists.
